Why red, green, blue and yellow? They are all primary colors, and contrast well to the human eye
GREEN is NOT a primary color!!! This is one of my biggest pet peeves. Green is a secondary color along with purple and orange, it is made by combining yellow and blue.
I work in the TV industry and so many people believe green is a primary color because they see "RGB" monitors (ok that was a while ago), or the red green and blue connections on HD TVS, "they must all be primary colors". Argh!
Red, green, and blue are the primary colors of light. They are the primary colors because they correspond to the three color receptors in our eyes.
Cyan, magenta, and yellow are the primary colors of ink. They are the *opposites* of red, green, and blue, respectively. Ink works subtractively -- you start from white and remove color -- while light works additively -- you start from black and add. This is why their primary colors are opposites.
The primary colors of ink are often simplified to blue, red, an
That is absurd. We evolved those three specific colors color receptors because they worked reasonably well for distinguishing objects. We could also just as easily have evolved violet, cyan, and orange color receptors.

Other way around.
Our eyes have red, green, and blue receptors because those are the primary colours [of light].
