Which of the following is an example of a primary color?

Blue is classified as a primary color because it cannot be created by mixing other colors together. In the traditional color wheel based on pigment, primary colors consist of red, yellow, and blue. These colors serve as the foundational building blocks for creating a wide array of other colors through various combinations. For instance, mixing blue with yellow produces green, and combining blue with red results in purple. Understanding primary colors is essential for artists because they allow for the creation of secondary colors, which can be further combined to produce a diverse spectrum of hues.
