“Color is infinitely shifty. It’s unstable in the presence of nearby colors. It’s vulnerable to tricks of the light. It acts like it’s moving when it’s not. It can act like it’s there when it’s not. Put another way, color is subject to a thousand kinds of distortion as it travels from an object, through light, through your eye to your (acculturated) brain. Yet the tricky, interwined science and art of color perception still goes under-appreciated.”
Color is still not well understood in digital design.
