Which of the following is classified as a secondary color?

The classification of colors is based on the color wheel, which distinguishes between primary and secondary colors. Primary colors are red, yellow, and blue. Secondary colors are created by mixing two primary colors.

Orange is classified as a secondary color because it is formed by mixing red and yellow. This blending of the two primary colors results in the creation of orange, thus confirming its status as a secondary color.

In contrast, red, yellow, and blue are all primary colors and cannot be created by mixing other colors. Understanding this foundational concept of color theory is essential for anyone studying visual arts, as it forms the basis for color mixing and the creation of various color palettes.
