I have always believed people could see a different range of color. I know women who can see fifty shades of green in a field of wheat. They have a sureness about color, an understanding, that goes way beyond mine.
Cosmic Star by Jane Sassaman
Most people have genes for three color receptors; tetrachromats have four. These tetrachromats are always female and they make up 12% of the population (both men and women? or just women?)

A figure bandied about is that tetrachromats see 100x the color of trichomats---the majority of the population with the usual three receptors.

The receptors are the cones.
That's the extent of my genetics and physiology knowledge.
Rods and cones.
Rods see black and white; cones see color.

Not only am I surrounded by probable tetrachromats in my business
of quilt and fabric design...

But many of my friends seem to have a skill that is way beyond what I see.

Without a genetic test it's not possible to determine just who's a 4 and who's a 3.
Bobbi Finley, Alfie Dreams
But I have my suspicions.

I would imagine many of you are tetrachromats, as are bumblebees and zebra finches.

I first read about this in an article in December's Vogue (always a reliable science source) but here are some other links:
