What are the primary color groups in color theory?

The primary color group in color theory consists of red, blue, and yellow. These colors are considered primary because they cannot be created by mixing other colors together. They serve as the foundational building blocks for color mixing. When combined in various ways, primary colors can produce a wide range of other colors. For instance, mixing red and blue yields purple, while blending yellow and blue creates green.

Understanding the significance of primary colors is essential in both traditional and digital art practices, as it informs how artists create new hues and tones. The other color groups mentioned do not serve the same foundational role. For example, green, purple, and orange are secondary colors, created by mixing two primary colors together. Black, white, and gray are neutral colors related to the color value and tone rather than being part of the primary color group. Lastly, red, green, and blue represent the additive color model used in digital displays, but they do not align with traditional color theory's primary colors in the context of paint or pigment.
