favorite colour

[Mystical]

Just because you can see it and be equally titillated by it doesn't mean others do.

For the record, I don't like pink. It doesn't fit any color scheme in my head and I find it a turn off. Red, however, gets my attention.

This made me remember something I'd read a while back, as to the color red. Red to men is brighter than the way women see it. I saw this video about testing men's gratuitous ability on the street when the woman was wearing certain colors: Red always won. Just a heads up, chumps

I also read this article, which took me a bit to find again but whatever. Looks like women and men dont see things eye to eye after all. Whod'a thunk?

National Geographic: Men and Women see colors differently

In color experiments the men and women tended to ascribe different shades to the same objects. The researchers think they know why.

"Across most of the visible spectrum males require a slightly longer wavelength than do females in order to experience the same hue," the team concludes in the latest issue of the journal Biology of Sex Differences.

Since longer wavelengths are associated with "warmer" colors, an orange, for example, may appear redder to a man than to a woman. Likewise, the grass is almost always greener to women than to men, to whom verdant objects appear a bit yellower.

The vision findings support the so-called hunter-gatherer hypothesis, which argues that the sexes evolved distinct psychological abilities to fit their prehistoric roles, the team says. (See "Sex-Based Roles Gave Modern Humans an Edge, Study Says.")

Noting that men in the study showed "significantly greater sensitivity for fine detail and for rapidly moving stimuli," the researchers write that their hunter forebears "would have to detect possible predators or prey from afar and also identify and categorize these objects more easily."

(See "Video Games Improve Vision, Study Says.")

Meanwhile, the vision of female "gatherers" may have become better adapted recognizing close-at-hand, static objects such as wild berries.

I know I'm a dork, but these things are interesting to me. Color is intriguing to me, as an artist I see daily life differently than others and am told I do quite often. It makes me happy to show others what I see through my eyes, with my photography and art.

Normally, people have three types of cone cells for daylight, for detecting different colors. But some women can see extra colors as they have four types of cone cell receptors. They are called tetrachromats. Compared to them, we all are color blind.

The first tetrachromat woman was discovered by researchers at Cambridge University in 1993. This is perhaps the most remarkable human mutation ever detected. The fact that all tetrachromats are female intrigued scientists. Now two scientists, working separately, want to investigate systematically for tetrachromats to clarify more about their existence and how they detect colors.

All mammals descended from nocturnal tree dwellers, which were colorblind, but the line of primates had more advantages in developing color vision for finding fruit food. Human color vision is based on three forms of iodopsin (color pigments), each sensitive to a different light wavelength and is found in a different cone type. When a different cone type is stimulated, the brain reads it as a particular color.

The three iodopsins respond to red, green and blue; all the other colors are their combinations. Like all pigments, iodopsins are proteins encoded by DNA genes. The genes encoding the "red" and "green" iodopsins are located on the X sex chromosome, while the "blue" iodopsin is on a non-sexual chromosome.

That's why color-blindness mostly affects men: 8% of the Caucasian males; while under 0.5 % of Americana women present it. Women have X chromosomes: one from the mother and one the father, while men have just one X chromosome from the mother and an Y sex chromosome from the father (this one does not contain any iodopsin gene).

X chromosomes can be a "green" iodopsine or a slightly shifted "green" iodopsine, and a "red" iodopsine and a shifted "red" iodopsine. That's why a woman can carry 5 types of iodopsins: these four plus "blue", while a man just three (a green type, a red one plus blue).

A recent paper by Kimberly Jameson, Susan Highnote and Linda Wasserman of the University of California, San Diego, showed that up to 50 % of women carry 4 types of iodopsins and can employ their extra pigments in "contextually rich viewing circumstances".

For example, when looking at a rainbow, these females can segment it into about 10 different colors, while trichromat (with three iodopsins) people can see just seven: red, orange, yellow, green, blue, indigo and violet. For tetrachromat women, green was found to be assigned in emerald, jade, verdant, olive, lime, bottle and 34 other shades.
