Which of the following are the primary colors?

The primary colors are the foundation of color theory and are defined as colors that cannot be created by mixing other colors together. Red, blue, and yellow are considered primary colors in traditional color theory, and they form the basis for creating a wide variety of other colors through mixing.

When these primary colors are combined in various ways, they can produce secondary colors (such as green, orange, and purple) and further combinations can lead to a broader spectrum of colors. This foundational concept is essential in many fields, including art, design, and, in a more abstract sense, the study of visual perception.

Other choices include colors that are either secondary colors, shades, or in the case of black, white, and gray, neutral tones. Understanding primary colors is crucial for anyone involved in practices that require color usage, as it informs not only practical application but also the theory behind color mixing and perception.
