Color theory is the study of how colors interact and the visual effects of color combinations. 
The color wheel is a basic tool in color theory, organizing colors into primary, secondary, and tertiary categories. 
Primary colors—red, blue, and yellow—are the foundation and cannot be made by mixing other colors. 
Secondary colors—green, orange, and purple—are created by mixing two primary colors. 
Tertiary colors, such as red-orange and blue-green, are made by combining a primary color with a neighboring secondary color. 
Complementary colors are pairs that sit opposite each other on the color wheel, like blue and orange, and they create strong contrast when placed side by side. 
Other key concepts in color theory include warm and cool colors, analogous colors (colors next to each other on the wheel), and color harmony, which helps artists and designers create visually appealing combinations.
