Red, yellow, and blue are examples of what kind of colors on the color circle?

Red, yellow, and blue are considered primary colors in the color circle. These colors are fundamental because they cannot be created by mixing other colors together, making them the building blocks for all other colors. Primary colors can be combined in various ways to create secondary colors, which are formed by mixing two primary colors together. For instance, mixing red and yellow yields orange, while blue and yellow produce green. Understanding the concept of primary colors is crucial for various applications in art, design, and color theory, as they form the basis for creating a wide array of color combinations.
