What can be said about primary colors in the context of color theory?

In the context of color theory, primary colors are foundational colors from which a wide range of other colors can be created. The key characteristic of primary colors is that they cannot be produced by mixing other colors together. Traditional color theory identifies red, blue, and yellow as the primary colors in the subtractive color model, which is commonly used in art and design.

These colors serve as the building blocks for all other colors. By mixing primary colors in various combinations and proportions, a vast spectrum of secondary and tertiary colors can be generated. Thus, when discussing the unique role of primary colors, it is essential to understand that they possess this essential property of being the source from which other colors arise, very much affirming the statement that they cannot be created by mixing other colors.
