Which of the following are considered primary colors in art?

Primary colors in art are considered to be red, blue, and yellow. These colors serve as the foundation for mixing and creating a wide range of other colors. They are termed "primary" because they cannot be created through the mixing of other colors. Instead, they are the building blocks from which secondary colors (like green, orange, and purple) can be formed by combining two primary colors.

In traditional color theory, which is often used in art and design, red, blue, and yellow are recognized as the primary colors for mixing pigments. This understanding allows artists to create many hues and shades by blending these primary colors in various proportions.

The other options list different combinations that either include secondary colors, which are derived from mixing the primary colors, or utilize color mixing models like additive (where red, green, and blue are primary colors) or subtractive (where yellow, cyan, and magenta are primary in printing). However, those do not pertain to the fundamental primary colors in traditional art practices.
