Red Light For Your Eyes
Declining eyesight can be improved by looking at red light, pilot study says. Red lights can help prevent damage to mitochondria in the retina, which leads to declining eyesight. It will be as easy as brushing your teeth or shaving, and as long as future studies support it, it just might save your eyesight.
Here’s the scoop on it from CNN:
A few minutes of looking into a deep red light could have a dramatic effect on preventing eyesight decline as we age, according to a new study published this week in The Journals of Gerontology.
If the results are replicated in future studies, and approved by the US Food and Drug Administration, the light could augur a new era in which millions of people have access to the easy home-based therapy. It would give them a new layer of protection against the natural aging processes that steal our eyes’ sensitivity to light and ability to distinguish colors.
“You don’t need to use it for very long to start getting a strong result,” said lead author Glen Jeffery, a professor of neuroscience at University College London’s Institute of Ophthalmology.
The science works, Jeffery said, because the light stimulates the health of mitochondria, which are like batteries in our cells.
And because mitochondria are implicated in a broad range of diseases, insights like these could help lead to new treatments for diseases including Parkinson’s and diabetes.
All it takes is a few minutes.
The study was small, a pilot study to test the concept. Researchers recruited 12 men and 12 women, whose ages ranged from 28 to 72. Each participant was given a small handheld flashlight that emitted a red light with a wavelength of 670 nanometers. That wavelength is toward the long end of the visible spectrum, and just short of an infrared wavelength, which tends to be invisible to the human eye.
They spent three minutes each day looking into the light over a period of two weeks.
The lights work on both cones and rods in the eye. Cones are photo receptor cells that detect color and work best in well-lit situations. Rods, which are much more plentiful, are retina cells that specialize in helping us see in dim light, according to the American Academy of Ophthalmology.
Researchers measured the cone function in subjects’ eyes by having them identify colored letters with low contrast. And they measured their eyes’ rod sensitivity by asking them to detect light signals in the dark.
There was a 14% improvement in the ability to see colors, or cone color contrast sensitivity, for the entire two dozen participants.
Improvement, however, was most significant in study participants over age 40. For those ages, cone color contrast sensitivity rose by 20% over the course of the study.
That age bracket also saw significant increases in rod threshold, which corresponds to the ability to see in low light. Study participants under 40 also experienced some improvement, but didn’t see the same jump as older subjects. Younger eyes haven’t declined as much as older eyes.
“The retina ages faster than any other organ in your body,” Jeffery said. “From an evolutionary perspective, we fundamentally have never lived past 40.”
Now, of course, we regularly live well beyond that age, and need ways to nurture the organs that for millennia have been the most likely to wear out earliest in life.
Researchers from University College London used small red lights like this one to stimulate retina mitochondria with the goal of stoppying eyesight loss.
Adults ages 40 and higher are are at the highest risk for eye diseases such as cataracts, diabetic retinopathy, glaucoma and age-related macular degeneration, according to the US Centers for Disease Control and Prevention.
These diseases can occur in young people but their prevalence increases with age. At the beginning stages, these conditions are treatable, although they can start creeping in before symptoms appear.
That’s why the AAO recommends increasing regular eye exams to every two to four years for people once they cross age 40, and to increase exams to every one to two years at age 65.
The CDC notes that the progression of these diseases can also be slowed by eating a diet rich in antioxidants and maintaining normal levels of blood sugar, body weight and blood pressure. If those indicators get out of normal range, they can further degeneration by breaking down blood vessels in the eyes, the American Heart Associations says.
It’s easy and safe to use
This new study in humans builds on results in fruit flies and in mice, which also showed that red light could improve the functioning of mitochondria.
For instance, a 2015 study showed that near-infrared light could spur energy production, improve mobility and extend the lifespan of fruit flies. And a 2017 study of visible red light at the edge of infrared reported a 25% improvement in the functioning of retinas in mice.
Longer-term independent safety studies of red lights in humans would have to garner similar benefits for this method of eyesight protection to be approved by the FDA. If so, you’d still need to use a properly vetted product under a doctor’s supervision.
For example, while the laser pointers approved by the FDA for sale in the US don’t cause eye damage, a 2018 case study in the New England Journal of Medicine outlined how a boy in Greece permanently injured an eye by pointing a green laser pointer into it.
One of the best assets of the red lights they used is that they are safe, Jeffery said. The researchers all tested the red lights on their own eyes before beginning the study and have found no ill effects.
The research subjects in the study also reported no ill effects. “If you use this every day, we have no evidence to say it’s detrimental,” Jeffery said.
That fits with prior research, in which the safety of red lights has long been established, explained Dr. Raj Maturi, an associate professor at Indiana University School of Medicine. It would be a very easy pathway to FDA approval,” he said. But more studies are needed to prove it helps. Although these lights aren’t harmful, Maturi wasn’t ready to embrace the idea that they’re incredibly helpful either.
This pilot study lacked a control group of patients who could have been exposed to a dummy light that emitted, he noted. The results found in this small study of 24 participants might not bear out in the larger population. Of the subjects over 40 in this study, individual characteristics of a few of them would be enough to make the eyesight improvements look stronger than they actually are.
“The data set could be brought down by three or four subjects,” he said. And while participants improved in how they saw the blue color axis, Maturi pointed out that they didn’t have statistically significant gains in how they saw the red color axis. To really test these insights, it’ll take a double-blind controlled study with a larger group of subjects and longer monitoring over time.
LED lights could help with many diseases
LED lights work in this arena because of what scientists call the mitochondrial theory of aging, in that humans and animals age as damage accumulates in mitochondria and mitochondrial DNA.
Therefore stimulating mitochondria to reduce damage is a way of slowing aging in general. Our retinas are chock-full of mitochondria — the highest concentration of mitochondria of any part of the body.
That’s a main reason why Jeffery and his colleagues sought to test out the red lights in a specific area of aging such as eyesight decline. Mitochondria absorb longer wavelengths of light, making the near-infrared light their preferred choice to test.
Red lights can improve function in a range of diseases, particularly in the mitochondria in those undergoing aging with conditions such as Parkinson’s, he noted. “Every disease could have a mitochondrial angle,” Jeffery said. “In diabetes, for instance, your mitochondria are very upset.”
Each application carries that same human desire to fend off processes that are both natural and universal. “We’re all going to suffer from aging. So let’s try to go gently if we can,” he said.
Color Psychology: How to Make Your Home Feel Good
Ready to paint? A little color psychology may be just what you need to create soothing and productive moods.
Home decor is often viewed as simply a matter of aesthetics — what looks attractive. But proponents of color psychology believe that the colors you use to decorate your home can have a profound effect on the emotional well-being of you and your family.
“Color is a universal, nonverbal language, and we all intuitively know how to speak it,” says Leslie Harrington, a color consultant in Old Greenwich, Conn. and a noted expert on the use of color in residential and industrial decor. “What color you paint your walls isn’t just a matter of aesthetics. It’s a tool that can be leveraged to affect emotions and behavior.”
If you like the idea of using color to create an emotionally healthy home, color consultants say you should first consider the primary function of each room. Next, pick a predominant color. Although it can’t be proven scientifically, color consultants say some hues work better than others at encouraging certain activities. Need ideas? Here’s a room-by-room rundown of the colors believed to work best in each of the most important rooms of your home, and the moods they create.
Living room and foyer paint colors.
Warm tones like reds, yellows, and oranges, and earth tones like brown and beige often work well in both the living room and foyer, because they’re though to stimulate conversation. “These are colors that encourage people to sit around and talk,” says Kate Smith, a color consultant in Lorton, Va. “You feel the warmth, the connection with other people.”
Kitchen paint colors.
Color consultants say that if you have fond memories of spending time in the kitchen when you were a kid, it might make sense to recreate the color scheme in your grown-up kitchen. “If you grew up in a blue-and-white kitchen and have great memories, blue and white may be the best colors for you and your family,” says Smith.
If there’s no particular paint scheme you remember fondly, reds and yellows can be great colors in the kitchen as well as in the living room and foyer. But watch out if you’re watching your weight: in addition to stimulating conversation, color consultants say that red may prompt you to eat more, if only subtly. “If you’re on a diet, you might want to keep red out of the kitchen,” Harrington says, adding that the restaurant industry has long recognized the appetite-stimulating power of red decor.
Dining room paint colors.
Because it’s stimulating, red decor can be great for a formal dining room. In addition to encouraging conversation, it whets the appetites of your guests. “If your dining room is red, people may think you are a better cook,” says Harrington.
Bedroom paint colors.
The bedroom is where you go to relax and reconnect with your partner. Cool colors — blues, greens and lavenders — can be great choices here, because they are thought to have a calming effect. The darker the hue, the more pronounced the effect is believed to be. “Reds tend to increase blood pressure and heart rate and stimulate activity,” says Harrington. “Blue does just the opposite. That’s why we think of it as calming.”
What if your teenager has a few ideas about how to paint his or her bedroom? In the name of family harmony, it probably makes sense to let your teen pick the paint — within reason. Harrington says she let her own daughter pick a wild paint scheme for her room — with the proviso that her daughter would repaint it white when she moved out.
Bathroom paint colors.
Whites and warm colors have always been popular choices for bathrooms, in large part because they connote cleanliness and purity. But nowadays the bathroom is used not just as a place to wash up, but also as a private retreat for relaxation and rejuvenation. Says Harrington: “Most people feel comfortable with blues and greens and turquoises because these colors give a sense of being clean and fresh — and calm.”
But spa colors in the bathroom make sense only if they flatter you. “When you look in the bathroom mirror, you want to look great,” says Smith. “If you would never wear a particular color, don’t paint your bathroom that color. That’s a recipe for disaster.”
Workout room paint colors.
“Reds and oranges can help you move,” says Harrington. “But they can also make you feel hot.” For this reason, blues and greens may be better choices here. Harrington says that yellow-greens and blue-greens may be the best choices because, in terms of color psychology, they’re “happier.”
Home office paint colors.
The name of the game here is productivity: the faster you complete work-related tasks, the more time you’ll have to spend enjoying family and friends. And color consultants agree that green can be a great choice for a home office. “Green is the color of concentration,” says Harrington. “It’s one of the best colors to be surrounded by for long periods of time.”

Why Is The Sky Blue?
We see a blue sky, because of the way the atmosphere interacts with sunlight.
White light, including sunlight, is made up of many different colors of light, each with its own corresponding wavelength.
Several different things can happen when this light encounters matter.
For instance, if sunlight passes through a transparent material, such as water, those light waves will refract, or bend, because light changes speed as it travels from one medium (air) to another (water). Prisms break up white light into its constituent colors, because different wavelengths of light refract at different angles — the colors travel at different speeds — as they pass through the prism.
Alternatively, some objects, such as mirrors, reflect light in a single direction. Other objects can cause light to scatter in many directions.
The blueness of the sky is the result of a particular type of scattering called Rayleigh scattering, which refers to the selective scattering of light off of particles that are no bigger than one-tenth the wavelength of the light.
Importantly, Rayleigh scattering is heavily dependent on the wavelength of light, with lower wavelength light being scattered most. In the lower atmosphere, tiny oxygen and nitrogen molecules scatter short-wavelength light, such blue and violet light, to a far greater degree than than long-wavelength light, such as red and yellow. In fact, the scattering of 400-nanometer light (violet) is 9.4 times greater than the scattering of 700-nm light (red).
Though the atmospheric particles scatter violet more than blue (450-nm light), the sky appears blue, because our eyes are more sensitive to blue light and because some of the violet light is absorbed in the upper atmosphere.
During sunrise or sunset, the sun’s light has to pass through more of the atmosphere to reach your eyes. Even more of the blue and violet light gets scattered, allowing the reds and yellows to shine through.

Blue – In Depth
In Egypt, blue was associated with the sky and with divinity. The Egyptian god Amun could make his skin blue so that he could fly, invisible, across the sky.
Blue could also protect against evil; many people around the Mediterranean still wear a blue amulet, representing the eye of God, to protect them from misfortune. In Islam,blue (including turquoise) is the color both of religion and community and is often used for decorating mosques.
In Greek and Roman days, blue symbolism was associated with the sky gods Jupiter, Juno and Mercury. In Judaism, blue symbolism is connected to God the Father. In the Catholic Church, blue symbolism is most closely related to the Virgin Mary, the Queen of Heaven.
Blue symbolism associates blue with freedom, strength and new beginnings. Blue skies are emblematic of optimism and better opportunities. Blue is the color of loyalty and faith. Blue is power. Blue is also the color of protection. Blue symbolism is nearly universal in meaning. As a result, blue is used in national flags and symbols around the world, including the flag of the United Nations.
Blue represents water, the source of life. Agricultural people have traditionally worshiped water in the form of rivers, clouds, mist and rain. Many favorite garden flowers are also blue, including delphinium, larkspur, pansies, irises, anemone, bluebells, hyacinth, lobelia, veronica, and ageratum.
Although blue is even more popular in the western world than is other areas of the world, blue skies and blue water are full of positive meaning in every culture. We are, after all, living on the “blue planet.”
Etymology:
The English language commonly uses “blue” to refer to any color from navy blue to cyan. The word itself is derived from the Old French word bleu.
The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. In Russian and some other languages, there is no single word for blue, but rather different words for light blue (голубой, goluboy) and dark blue (синий, siniy).
The root of these variations was the Proto-Germanic blaewaz, which was also the root of the Old Norse word bla and the modern Icelandic blar, and the Scandinavian word bla, but it can refer to other colors.
A Scots and Scottish English word for “blue-grey” is blae, from the Middle English bla (“dark blue,” from the Old English blood). Ancient Greek lacked a word for color blue and Homer called the color of the sea “wine dark”, except that the word kyanos (cyan) was used for dark blue enamel.
Several languages, including Japanese, Thai, Korean, and Lakota Sioux, use the same word to describe blue and green. For example, in Vietnamese the color of both tree leaves and the sky is xanh. In Japanese, the word for blue (青 ao) is often used for colors that English speakers would refer to as green, such as the color of a traffic signal meaning “go”.

Migraine Cure with Red / Green
I have had good success eliminating a migraine prodrome aura. I cured it by using a special eye exercise. The procedure was intended to work the eyes and the visual centers of the brain harder than usual by forcing them to do a cross-eye fusion procedure. The speculation behind the possible success using this method was based upon a reported brain scan done during migraine attacks which showed an abnormal blood flow to the visual cortex located in the back of the brain. These cross-eye procedures force the brains visual centers to do far more work than is usually required of them and that forces the brain to allocate the blood flow in a different way from what they were doing to create the migraine aura.
This is an experimental procedure which I performed upon myself. I am only reporting what appeared to work for me and I do not necessarily suggesting that you try the experiment so any results you may have, good, bad or inconclusive are strictly upon your own recognizance. However, below are the cross-eye charts which I used successfully to eliminate my visual hallucinations in about three minutes. Usually it takes about 30 to 50 minutes in a dark room with a hot or cold bag on the back of my head to clear up the aura. I have tried both the hot and cold treatments but found that tapping the back of the head worked better. But this cross-eye treatment worked best of all.
What works for me is to look cross-eyed at my finger tip held between the flags about half way to the screen and then to slowly move it towards and away from my face while looking at my finger tip and thinking about the dot. At some point the central dots from the opposite fields fuse into one. When they fuse I slowly lower my finger out of sight while watching the dot. And then in about twenty seconds the light show begins. With Red-green target #36 I like to move my stare between the various smaller dots around the center and to slowly read the numbers and letters. If my eyes uncross I return my finger to the position where fusion took place and can usually get the fusion back in a few seconds.
Here is a different graphic to play around with:
I created these pictures for the cross-eye fusion experiments but I discovered that they confused my visual centers so much that the effort of fusion soon forced my brain to abandon migraine auras and give its attention to the fusion. Even under normal non-aura brain functioning these pictures created highly volatile liable images which will shift quickly through a variety of colors and golden blends.
For more detail on these cross-eye fusion experiments go to the previous mind fuzing experiments. Here is a group of similar eye experiments with more instructions on how to cross your eyes: Eye Experiments.
Please remember these are experiments and you are totally responsible for any strange effects or results. I intended them for learning how your perception works and how it sometimes does very strange and unexpected things.

Living Red
Instinctively, the occurrence of red makes us wary, as we connect it with heat and the potential danger of burning. Red lights are built into artificial fires to help simulate the coziness of a real fire. Too much heat and red burns, but at the right level it supports our lives and gives us comfort.
Being the color of blood, red has symbolic links with living and life. Spilling or losing blood brings illness and death. Wearing red, eating red foods and surrounding yourself with red increases the body’s ability to absorb iron, the metal that is responsible for the color of hemoglobin in the blood. The presence of hemoglobin allows the blood to absorb oxygen in the lungs and to transport that life-giving oxygen to the cells of the body.
Physical activity and the energy that that supports it also has a red vibration. If speed, danger, daring or courage are involved, the red quality of the activity increases. Mountaineers, racing car drivers, and stuntmen all have “red” careers.

Green – In Depth
When students were given creativity tests, those whose test-cover pages had a green background gave more creative answers than those whose pages were white, blue, red or grey. ~Sue Shellenbarger
Since the beginning of time, green has signified growth, rebirth, and fertility. In pagan times, there was the “Green Man” – a symbol of fertility. In Muslim countries, it is a holy color and in Ireland, a lucky color. It was the color of the heavens in the Ming Dynasty.
The word green comes from the Middle English and Old English word grene, which, like the German word grün, has the same root as the words grass and grow.
It is from a Common Germanic *gronja-, which is also reflected in Old Norse grænn, Old High German gruoni (but unattested in East Germanic), ultimately from a PIE root *ghre– “to grow”, and root-cognate with grass and to grow.
The first recorded use of the word as a color term in Old English dates to ca. AD 700.
Latin with viridis (and hence the Romance languages, and English vert, verdure etc.) also has a genuine term for “green”. Likewise the Slavic languages with zelenъ. Ancient Greek also had a term for yellowish, pale green – χλωρός, chloros (cf. the color of chlorine), cognate with χλοερός “verdant” and χλόη “the green of new growth”.
For the ancient Egyptians, green had very positive associations. The hieroglyph for green represented a growing papyrus sprout, showing the close connection between green, vegetation, vigor and growth.
In wall paintings, the ruler of the underworld, Osiris, was typically portrayed with a green face, because green was the symbol of good health and rebirth.
Palettes of green facial makeup, made with malachite, were found in tombs. It was worn by both the living and dead, particularly around the eyes, to protect them from evil. Tombs also often contained small green amulets in the shape of scarab beetles made of malachite, which would protect and give vigor to the deceased.
It also symbolized the sea, which was called the “Very Green. Interestingly, in Japan, the words for blue and green (“ao“) are the same.
Today, green is no longer just a color. It’s now the symbol of ecology and a verb. Today’s greens can be found in a wide range of objects: pea soup, delicate celadon glazes, sleazy shag carpet, sickly bathroom walls, emeralds, wasabi, and sage. The English language reflects some strange attributes: Would you rather be green with envy, green behind the ears, or green around the gills? (Idiomatic American English for extremely envious, immature or nauseated.)
Green in other cultures:
Green is usually considered lucky. A green shamrock symbolizes this. However, this is not always true in every culture, venue, or situation. For example:
- You won’t find many green cars at racetracks because they are considered unlucky.
- Circus and traveling showmen in Australia may consider green to be bad luck.
- An old English rhyme about wedding colors: “Married in green, Ashamed to be seen.”
- In China, Green may symbolize infidelity. A green hat symbolizes that a man’s wife is cheating on him.
- In Israel, green may symbolize bad news.
- In Spain, racy jokes are “green.”
Seeing Green:
There are more shades of green than that of any other color. Greens range from yellow-greens, such as lime and avocado greens, to those with a blue tinge (such as emerald). Aqua or turquoise are colors that are typically half green and half blue.
Color Blindness – Approximately 5% – 8% of men and 0.5% of women of the world are born colorblind. People who are protans (red weak) and deutans (green weak) comprise 99% of this group.
Some European countries have outlined certain traffic light colors so that it is clear which is green and which is red, by the color that has a rectangle around it. Some states in the U.S. have placed diagonal lines through green traffic lights as an aid for the colorblind.
Green exit signs have an important advantage when there is smoke in the air (in other words, when a fire is burning). With red exit signs, it looks like a fire – firemen have actually rushed into burning buildings and tried to put out the signs! With a green sign, people know it isn’t the fire itself but the way to safety.

Yellow – In Depth
The sound of colors is so definite that it would be hard to find anyone who would express bright yellow with bass notes or dark lake with treble… ~Wassily Kandinsky
The word “yellow” comes from the Old English geolu, geolwe, meaning “yellow, yellowish”, derived from the Proto-Germanic word gelwaz. It has the same Indo-European base, –ghel, as the word yell; –ghel means both bright and gleaming, and to cry out. Yellow is a color which cries out for attention.
The English term is related to other Germanic words for yellow, namely Scots yella, East Frisian jeel, West Frisian giel, Dutch geel, German gelb, and Swedish gul.
According to the Oxford English Dictionary, the oldest known use of this word in English is from The Epinal Glossary in the year 700.
In Ancient Egypt, yellow was associated with gold, which was considered to be imperishable, eternal and indestructible. The skin and bones of the gods were believed to be made of gold.
The Egyptians used yellow extensively in tomb paintings; they usually used either yellow ochre or the brilliant orpiment, though it was made of arsenic and was highly toxic. A small paintbox with orpiment pigment was found in the tomb of King Tutankhamun. Men were always shown with brown faces, women with yellow ochre or gold faces.
The Dark Side of Yellow
Yellow is the only color that reacts badly to black: Add a little black and it becomes a sickly yellow-green.
In some cultures and situations, the color yellow represents cowardice, betrayal, egoism, and madness. Furthermore, yellow is the color of caution and physical illness (jaundice, malaria, and pestilence). Perhaps it’s no coincidence that the sources of yellow pigments are toxic metals – cadmium, lead, and chrome – and urine.
The original formula for Indian yellow, the bright yellow long used in Indian miniatures was banned due to the way it was made. Cows were poisoned with mango leaves and the color was made from their urine.
In Russia, a colloquial expression for an insane asylum used to be “yellow house.” Bright “marigold” yellow may be associated with death in some areas of Mexico. Those condemned to die during the Inquisition wore yellow as a sign of treason.
A yellow patch was used to label Jews in the Middle Ages. European Jews were forced to wear yellow or yellow “Stars of David” during the Nazi era of prosecution.
Interestingly, in China, adult movies are referred to as yellow movies.
Seeing Yellow:
Although yellow occupies one-twentieth of the spectrum, it is the brightest color, the most luminous of all the colors. It’s the color that captures our attention more than any other color.
In the natural world, yellow is the color of sunflowers and daffodils, egg yolks and lemons, canaries and bees. In our contemporary human-made world, yellow is the color of Sponge Bob, the Tour de France winner’s jersey, happy faces, post its, and signs that alert us to danger or caution.

Orange – In Depth
“Orange is red brought nearer to humanity by yellow.”
— Wassily Kandinsky
The color orange is named after the appearance of the ripe orange fruit. The word comes from the Old French orenge, from the old term for the fruit, pomme d’orenge. That name comes from the Arabic naranj, through the Persian naranj, derived from the sanskrit naranga.
The first recorded use of orange as a color name in English was in 1512, in a will now filed with the Public Record Office. Before this word was introduced to the English-speaking world, the color was referred to as ġeolurēad (yellow-red).
In the 18th century, orange was sometimes used to depict the robes of Pomona, the goddess of fruitful abundance; her name came from the pomon, the Latin word for fruit.
Oranges themselves became more common in northern Europe, thanks to the 17th century invention of the heated greenhouse, a building type which became known as an orangerie.
Seeing Orange:
Orange is the color most easily seen in dim light or against the water, making it the color of choice for life rafts, life jackets or buoys. It is worn by people wanting to be seen, including highway workers and lifeguards. Prisoners are also sometimes dressed in orange clothing to make them easier to see during an escape. Lifeguards on the beaches of Los Angeles County, both real and in television series, wear orange swimsuits to make them stand out. The Golden Gate Bridge at the entrance of San Francisco Bay is painted international orange to make it more visible in the fog.

Red – In Depth
In ancient Egypt, red was associated with life, health, and victory. Egyptians would color themselves with red ochre during celebrations. Egyptian women used red ochre as a cosmetic to redden cheeks and lips, and also used henna to color their hair and paint their nails.
The word red is derived from the Old English rēd. The word can be further traced to the Proto-Germanic rauthaz and the Proto-Indo European root reudh-.
In Sanskrit, the word rudhira means red or blood.
In the Akkadian language of Ancient Mesopotamia and in the modern Inuit language of Eskimos, the word for red is the same word as “like blood”.
The words for colored in Latin (coloratus) and Spanish (colorado) both also mean red, whereas in Portuguese the word for red is vermelho, which comes from Latin vermiculus, meaning “little worm”.
In the Russian language, the word for red, Кра́сный (krasniy), comes from the same old Slavic root as the words for beautiful-красивый (krasiviy) and excellent-прекрасный (prekrasniy). Thus Red Square in Moscow, named long before the Russian Revolution, meant simply “Beautiful Square”.
Healthy people are often said to have a redness to their skin color (as opposed to be appearing pale). After the rise of socialism in the mid-19th century, red was used to describe revolutionary movements. The word is also obviously associated with anything of the color occupying the lower end of the visible light spectrum, such as red hair or red soil.
Red Indians is a British term for Native Americans. American terms for this ethnic group include redskin, redhead and red man, though they are not the preferred terms.
Seeing red:
The human eye sees red when it looks at light with a wavelength between 620 and 740 nanometers. Light just past this range is called infrared, or below red, and cannot be seen by human eyes, although it can be sensed as heat. Red light is used to help adapt night vision in low-light or night time, as the rod cells in the human eye are not sensitive to red.
