Why are primary colors called primary?

The colors red, blue, and green are called primary because by mixing just these three colors you can create all the colors in the spectrum. Most of the colors that you see are mixtures of two or more colors. The word “primary” is an adjective used to describe anything that occurs first, or is most important. It makes sense that we call these colors primary, since all other colors come from them!
