"Color perception: Not in beholder's eye"

ROCHESTER, N.Y., Oct. 25 (UPI) -- University of Rochester scientists say the first images of living human retinas have shown color perception differs dramatically among people.

The researchers found the number of color-sensitive cones in the human retina differs by up to 40 times among people, yet all people appear to perceive colors the same way.

The findings strongly suggest our perception of color is controlled much more by our brains than by our eyes....

"We've shown that color perception goes far beyond the hardware of the eye, and that leads to a lot of interesting questions about how and why we perceive color," he added.
