Which is NOT a primary color?

In the context of color theory, primary colors are the foundational colors that cannot be created by mixing other colors. The primary colors in traditional color theory, often used in art and design, are red, yellow, and blue.

Orange results from mixing red and yellow, which makes it a secondary color rather than a primary one. This fundamental understanding of color mixing highlights why orange is not classified as a primary color.

Recognizing primary colors is crucial for artists, as they serve as the building blocks for creating a wide spectrum of other colors through mixing techniques. Understanding this concept helps in mastering color selection and harmonization in various artistic practices.
