The reason green is not considered a primary color lies in the fundamental concepts of color theory. Primary colors are defined as the cornerstone colors that cannot be created by blending other colors together. In traditional color theory, specifically the RGB (Red, Green, Blue) model used in light and digital screens, the primary colors are red, green, and blue. However, in the RYB (Red, Yellow, Blue) model, which is often utilized in painting and art, the primary colors are red, yellow, and blue.

Since green is formed by combining blue and yellow, it is classified as a secondary color, rather than a primary one. In essence, it is crucial to recognize that primary colors serve as the base from which all other colors can be mixed, while secondary colors are the result of mixing two primary colors together.
