The term "primitive colors" can be replaced with several alternative words. Colors that are considered basic or essential could be referred to as "foundational colors." Additionally, the phrase "primary colors" is commonly used to describe the fundamental colors from which all other colors can be created. "Elemental colors" is another synonym that indicates a basic and natural color palette, whereas "rudimentary colors" implies a simple and unsophisticated color scheme. Lastly, "basic hues" or "fundamental shades" accurately convey the simplistic nature of primitive colors without devaluing their importance in art and design.
