Don't even bother making reddish green or yellowish blue colors. Your eyes simply can't see them:

Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.

The limitation results from the way we perceive color in the first place. Cells in the retina called "opponent neurons" fire when stimulated by incoming red light, and this flurry of activity tells the brain we're looking at something red. Those same opponent neurons are inhibited by green light, and the absence of activity tells the brain we're seeing green. Similarly, yellow light excites another set of opponent neurons, but blue light damps them. While most colors induce a mixture of effects in both sets of neurons, which our brains can decode to identify the component parts, red light exactly cancels the effect of green light (and yellow exactly cancels blue), so we can never perceive those colors coming from the same place.

If you browse reddit, you may have noticed that when someone posts a very old picture of a relative, someone always restores and colorizes it as a gift to the submitter. A lot of these amazing photo restorations are done by Swedish artist Sanna Dullaway. She has also colorized many historic photographs.

Dullaway recently started her own business in restoring old photographs, but the website is still under construction. But there are other places to see her work. Link to reddit album. Link to Dullaway’s Flickr stream. -Thanks, özi!

Love colors? Then staying at a boring ol' hotel simply won't do! Thank goodness Pantone came to the rescue!

Behold, the Pantone Hotel, a seven-story, 59-room hotel in Brussels by architect Olivier Hannaert and interior designer Michel Penneman. The colorful hotel utilizes a lot of colors from those color chips designers love so much.

I saw pictures of this place last year and could not find enough information about it to share, so I am delighted to find this article. A neighborhood found in Taichung City in Taiwan, a military dependents village founded over 50 years ago, is one of the most colorful places in the world, thanks to 86-year-old artist Huang Yung-fu.

Huang Yung-fu first picked up a paintbrush about two years ago. He started to paint for his own pleasure using the remains of the equipment from the art classes he attended when he was a child. Students of a university not far from the “painted military dependents’ village” seem to be among the first who discovered this old man’s talent and started to spread the news. Some even took pictures of the paintings and published them online. Information about his paintings went viral, to the point where tourists have flown in from Malaysia, Japan, and Korea to see them. The dull and drab military dependents’ village is now recognized as one of the must-see spots in central Taichung City.

The year 1931 stands out in the history of research about insane people’s favorite colors. That summer, Siegfried E. Katz of the New York State Psychiatric Institute and Hospital published a study called “Color Preference in the Insane.” The full citation is:

“Color Preference in the Insane,” Siegfried E. Katz, Journal of Abnormal and Social Psychology, vol. 26, no. 2, July 1931, pp. 203–11.

Assisted by a Dr. Cheney, Dr. Katz tested 134 hospitalized mental patients. For simplicity’s sake, he limited the testing to six colors: red, orange, yellow, green, blue and violet. No black. No white. No shades of gray.

“These colors,” he wrote, “rectangular in shape, one and one-half inches square, cut from Bradley colored papers were pasted in two rows on a gray cardboard. They were three inches apart. The colors were numbered haphazardly and the number of each color placed above it. The cardboard was presented to the patient and he was asked to place his finger on the number of the color he liked best. After he had made the choice he was asked in a similar manner for the next best color, and so on.”

Some of the patients “cooperated well”, and made six choices. Others, Dr. Katz reported, “quickly lost interest and made only one, two or three.”

Blue was the most popular color. Men, in the aggregate, then favored green, but the female patients were divided on green, red or violet as a second choice.

Patients who had resided in the hospital for three or more years were slightly less emphatic about blue. Dr. Katz says that these long-term guests were “those with most marked mental deterioration.” Their preference, as a group, shifted somewhat toward green and yellow. Those of longest tenure, though few in number, had a slightly elevated liking for orange.

The report is packed with tidbits that beg, even now, for further analysis:

==> “38 per cent of dementia praecox and manic-depressives, each, gave first preference to blue, and 42 per cent of all other patients.”

==> “Green received the first choice from 16 per cent of dementia praecox, 9 per cent of manic-depressives, and 13 per cent of other diseases.”

==> “For red as first choice, the percentage of votes were: Manic-depressives, 16; other diseases, 15; dementia praecox, 12. As second choice, they were: Manic-depressives, 22; dementia praecox, 18; other diseases, 13.”

==> “Orange and yellow were also best liked by manic-depressives; green by dementia praecox; and violet by all others.”

Dr. Katz foresaw practical applications for his research. He suggested that “in the furnishings of living quarters the selection of colors pleasing to special groups of patients might be worth consideration.”

Consciously or not, hospital staff seem to have followed Dr. Katz’s insights in fashioning their personal at-work appearance. The evocatively-named Bragard Medical Uniforms, a New York firm founded in 1933, now publishes a list of the most popular uniform colors. The list currently is topped by, in order: royal blue; dark grey (which, alas, Dr Katz excluded from his 1931 survey); dark green; and red.

Color Preference in the Insane Reconsidered

Dr. Katz’s findings were put to the test, partially, decades later in the study:

“The Relationship Between Color Preference and Psychiatric Disorders,” Cooper B. Holmes, H. Edward Fouty, Philip J. Wurtz and Bruce M. Burdick, Journal of Clinical Psychology, vol. 41, no. 6, November 1985, pp. 746–9.

The authors, at Emporia State University and at the Veterans Administration Hospital in Tuscaloosa, Alabama, explain, at the end of their study:

We realize that the reader may question whether the present study merely has added to the confusion about color preferences and personality and color preferences and psychiatric illness. We think not. Enough studies have been reported to present a consistently inconsistent picture of the relationship. That is, it is apparent that a clear-cut relationship between color and psychiatric illness has not been established, and our study continues to show that pattern. This brings into question the use of color in psychiatric diagnosis.

Recently a couple decided to raise their child non gender specific and let their baby decide for his or herself what toys, clothes and colors they preferred. This study shows how men and women differ on color preferences. So this begs the question, are our color preferences influenced by our gender?

From the day that babies are brought home and cradled in their pink or blue blankets, implications have been made about gender and color. While there are no concrete rules about what colors are exclusively feminine or masculine, there have been studies conducted over the past seven decades that draw some generalizations.

Keep your eyes fixed on the small white mark in the center. At first, the ring is stationary and it’s easy to tell that the dots are changing. A few seconds later, the ring begins to rotate and the dots suddenly appear to stop changing.

But play the movie again, this time looking directly at one of the dots and following it as the ring rotates. You will see that, in fact, the dots had been changing the whole time, even during the rotation—you just didn’t notice it. This failure to detect that moving objects are changing is silencing.

The findings were published in the journal Current Biology, with an abstract available online. Link -Thanks, Rob Hartmann!

Most insects have wings that appear to be transparent. Researchers from the University of Lund have found that they actually have rainbow colors, but the background of those wings makes all the difference in what the human eye sees.

“You hold the wing up against the light, so you can see the veins,” said study co-author Daniel Janzen, an evolutionary ecologist at the University of Pennsylvania. “If you’re looking through a microscope, you try to get a clear view behind the wing. It’s the antithesis of getting wing color.”

The researchers studied wings under microscopes, against black backgrounds. But once Janzen, who breeds wasps for his research on caterpillar-parasite symbioses, started to look, colors could be seen by the naked eye as wings passed over insects’ black bodies.

This study looked at the wings of wasps and flies, and the team believes they may find similar results in other orders of insects. Link

Bulls care little about the redness of a matador’s cape. Psychologists have been pretty sure about that since 1923, when George M. Stratton of the University of California published a study called “The Color Red, and the Anger of Cattle.” The full citation is:

“The Color Red, and the Anger of Cattle,” George M. Stratton, Psychological Review, vol. 30, no. 4, July 1923, pp. 321–5.

“It is probable,” Professor Stratton opined, “that this popular belief arises from the fact that cattle, and particularly bulls, have attacked persons displaying red, when the cause of the attack lay in the behavior of the person, in his strangeness, or in other factors apart from the color itself. The human knowledge that red is the color of blood, and that blood is, or seemingly should be, exciting, doubtless has added its own support to this fallacy.”

Professor Stratton, aided by a Miss Morrison and a Mr. Blodgett, conducted an experiment on several small herds of cattle,forty head altogether: a mixture of bulls and bullocks (castrated bulls) and cows and calves, including some who were accustomed to wandering the range and others who lived in barns.

The researchers obtained white, black, red and green strips of cloth, each measuring two by six feet. These they attached “endwise to a line stretched high enough to let the animals go easily under it; from this line the colors hung their 6 feet of length free of the ground, well-separated, and ready to flutter in the breeze.” (Image credit: Flickr user inthesitymad)

The cattle showed indifference to the banners, except sometimes when a breeze made the cloth flutter. Males and females reacted the same way, as did “tame” and “wild” animals. Red did nothing for them.

Farmers seem to have already suspected this. Professor Stratton surveyed some. He reports that “Of 66 such persons who have favored me with their careful replies, I find that 38 believe that red never excites cattle to anger; 15 believe that red usually does not excite them to anger, although exceptionally it may; 8 believe that it usually so excites, though exceptionally it may not; and 3 believe that it always so excites.”

One of those three dissenters described her experience with red-hating cattle: “A lively little Jersey cow whom I had known all her six years of life, chased me through a barbed wire fence when I was wearing a red dress and sweater, and never did so before or after. I changed to a dull gray, and reentered the corral, and she paid no attention to me, and let me feed and water her as usual. Also a Durham bull whom I had raised from a calf, and was a perfect family pet, chased me till I fell from sight through some brush when I was wearing the same outfit of crimson.”

More typical, however, was the farmer who told Professor Stratton: “In referring to the saying, ‘Like waving a red rag before a bull,’ I have found that to wave anything before a bull is dangerous business.” (Image credit: Flickr user Multimaniaco)

George Eastman House is the repository for many of the early tests made by the Eastman Kodak Company of their various motion picture film stocks and color processes. The Two-Color Kodachrome Process was an attempt to bring natural lifelike colors to the screen through the photochemical method in a subtractive color system. First tests on the Two-Color Kodachrome Process were begun in late 1914. Shot with a dual-lens camera, the process recorded filtered images on black/white negative stock, then made black/white separation positives. The final prints were actually produced by bleaching and tanning a double-coated duplicate negative (made from the positive separations), then dyeing the emulsion green/blue on one side and red on the other. Combined they created a rather ethereal palette of hues.”

In an essay at The Telegraph, photography critic and picture editor Lucy Davis muses about the palettes used by well-known artists.

Some artists mix every gradation of colour they will need for a painting before they start, others as they need them. “My freshly arranged palette, brilliant with contrasting colors, is enough to fire my enthusiasm,” noted Delacroix in his Journal in 1850. The French artist was meticulous in his arrangement of colours, and when unwell, would take his palette to bed and spend the entire day just mixing new shades.

The actual palettes of Renoir, Seurat, Degas, Delacroix (above), Moreau, Gauguin, and Van Gogh are illustrated, accompanied by commentary on how the physical layout of colors on the board may influence the figurative “palette” of color choices used by the artist for his work.

The authors here propose that humans prefer colors like blues and greens because those colors and ecologically healthy (blue skies, clean water, healthy vegetation), and do not prefer colors like brown because it’s associated with stuff that is ecologically unhealthy (like crap and things that are rotting).

Then they went about testing the theory by correlating color preference with objects that were judged favorable or unfavorable by the test subjects. Although the ecological theory incorporates parts of several other color theories, the data seems to support this idea more than previous theories. Link

This color is also known as basic green 4 and is often used when creating a green dye. This vibrant green comes from the carbonate mineral known as Malachite, or copper carbonate. In the 1800, the mineral was widely used for green paints because it was lightfast and often varied in color. The color is one that is seen rampant in history. For instance, there is the Malachite Room in Hermitage, and it is also said that Demeter’s throne was made of this color as well.

"Turquoise is universally appealing. It puts everyone in the same state of mind — on vacation," says Jane Schoenborn, design director at Lilly Pulitzer. "Turquoise for us is a really big color. A lot of times it’s transporting, whether you’re actually going to a resort destination or not."

Leatrice Eiseman, executive director of the Pantone Color Institute, says there was no runner-up to turquoise in her mind because people crave escapism and freshness after a tough year. The shade is on the cusp of blue and green, which makes it both inviting and serene — characteristics associated with blues — and invigorating and luminous, which comes from green, she says.

"Transporting" was a word many used for turquoise, a shade that takes designer Tommy Hilfiger to the beach, especially the Caribbean, St. Tropez, France, or Southern California, which served as the inspiration for his newest collection. In jewelry, he thinks of the American Southwest, or Central or South America.

Early in May, 1945, officers from the German army and Gestapo met with Allied commanders, including Field Marshall Montgomery to offer their country’s surrender at his headquarters near Hamburg.  Interestingly, the only color photographs of this event were taken by a clerk, Ronald Playforth, who hid in the trees during the meeting.

Thequintessential wrote a brief synopsis of this event:

His pictures show Admiral Hans Georg von Friedeburg, the most senior member of the delegation, General Eberhard Kinzel, chief of staff of the north west Germany army, and Major Friedl, a 6ft 6ins Gestapo chief. They were received by Field Marshall Montgomery, with his customary black beret and army uniform, who, when the Germans tried to negotiate, reportedly gave them a ‘tongue lashing’ about the bombing of Coventry and the horrors of Belsen. The delegation reported back to their HQ and Admiral Karl Doenitz – Hitler’s successor – and were given permission to sign the surrender papers, which they did the next day, May 4. When it was all over Montgomery is said to have leaned back and said simply: ‘That concludes the surrender.’

Using a list of countries generated by The World Factbook database, flags of countries fetched from Wikipedia are analysed by a custom made python script to calculate the proportions of colours on each of them. That is then translated on to a piechart using another python script.

John Breach, chairman of the British Independent Fruit Growers Association, said: ‘I’ve never seen this happen before to a Golden Delicious. It is extremely rare. It is an extreme mutation.

‘There has been the occasional case of this type reported. If there was a whole branch of apples with the same colouring then fruit experts would get even more excited.’

Jim Arbury, fruit superintendent at RHS Garden Wisley in Surrey, said it was probably the ‘result of a random genetic mutation’.

‘This is known as a chimera where one of the first two cells has developed differently giving rise to one half of the apple being different,’ he said.

Perhaps the most surprising and most exciting application of this research is that it may allow us to predict the colors of many dinosaurs.

“These include many of our most well loved dinosaurs,” says Prum. “Like velociraptor, the dinosaur that chased the kids around the kitchen in Jurassic Park, was actually fully plumaged.”

While these dinosaur feathers were not used for flight until the appearance of the transitional species Archaeopteryx, the first known bird, they were probably useful for warmth. Prum says we could even learn more about the color of one of the most famous dinosaurs of all, Tyrannosaurus rex.

“In the classic mural The Age of Reptiles in the Yale Peabody museum, they depicted T-rex, which is one of the iconic, huge, bipedal, meat-eating dinosaurs,” he says. “Recent fossil discoveries have shown that the closest relative of these huge tyrannosaurids actually had tiny skin appendages or fossil feathers—’dino-fuzz.’

In India, a newly discovered color-changing frog has been worshipped as a god. Reji Kumar, the person who found it, keeps the frog in a glass jar at his home where hundreds of people come to see it every day.

Apart from the obvious biological findings this hopping lava lamp can provide, it also gives an additional insight as to how religions and spiritual groups can emerge. I don’t blame them either. Who needs color-saturating hallucinogens for spiritual transcendence when you have a kaleidoscopic animal?

I say this new rainbow frog will become the new symbol for racial equality, just as long as it doesn’t croak (which is actually a concern).

The frog was a dazzling white colour when Reji, who is from Thiruvananthapuram, the capital of Kerala, in south India, first spotted it.

Then it changed to yellow and had gone grey by the time he got it home.

“By night the frog was dark yellow, and then it became transparent so you could see its internal organs,” Reji, a life worker, reportedly said.

How many animals do you suppose we pass in nature and never notice? Masters of evading humans and other predators, many creatures avoid being seen even at close range. Some of these are color-changers with amazing abilities to mimic not only their natural environs but even, in some cases, the behavior and movement of other species so they can pass as predators rather than as prey.

The ability to change color seems like an animal superpower at times – some of them can alter their appearance to blend with the colors, materials and textures of virtually any surroundings. For some this ‘costume change’ happens quickly, for others it is seasonal – for many it helps them avoid predators, for a few it enables them to sneak up on prey. Culled from around the animal kingdom, here are seven of most impressive color-changing species in the world.
