Some women may see 100 million colors, thanks to their genes

Susan Hogan can't be sure, but it wouldn't surprise her if she turned out to be a tetrachromat.
A tetrachromat is a woman who can see four distinct ranges of color, instead of the three that most of us live with.
A genetic test would be needed to verify whether Mrs. Hogan truly fits that description, but it could help explain why the interior decorator can hold up three samples of beige wall paint, "and I can see gold in one and gray in another and green in another, but my clients can't tell the difference."
It may be impossible for us trichromats to imagine what a four-color world would look like. But mathematics alone suggests the difference would be astounding, said Jay Neitz, a renowned color vision researcher at the Medical College of Wisconsin.

Dr. Neitz, who conducts his research with his wife Maureen, said only women have the potential for super color vision.
That's because the genes for the pigments in green and red cones lie on the X chromosome, and only women have two X chromosomes, creating the opportunity for one type of red cone to be activated on one X chromosome and the other type of red cone on the other one. In a few cases, women may have two distinct green cones on either X chromosome.

Far more likely that men just don't give a damn about shades of pinkish pearl whatever...
