Which colors are considered primary colors?

Primary colors are fundamental in color theory because they cannot be created by mixing other colors together. The traditional primary colors in art and design are red, yellow, and blue. These colors serve as the building blocks for creating a wide range of other colors. By mixing these primary colors in various combinations, one can produce secondary colors such as green, orange, and purple.

Understanding primary colors is essential for interior designers as they form the basis for color palettes and can influence the mood and atmosphere of a space. In contrast, the other options do not represent primary colors. Orange, green, and purple are secondary colors derived from mixing primary colors, while black, white, and grey are considered neutral colors that do not fit into the primary color framework. Red, green, and violet include a primary color (red) but the other two are not primary, which makes the first option the correct choice.
