About Trichromatic

What's black, white, and red all over? A newspaper! This punny joke is also trichromatic — that is, using three colors. "Chromatic" comes from the Greek "khrōma," meaning color.

Did you Know?

Most humans have trichromatic vision. There are three types of cone cells in the eye, which interpret different colors. These three colors are then transmitted to the brain to produce the vast array of colors you see. People with colorblindness cannot see one or more of these three colors.
