Expert Solution

Colour Theory

Color theory is the basis of the main rules and guidelines concerning color and its use in the creation of aesthetic images. By understanding the basics of color theory, you can begin to analyze the logical structure of colors on your own to create and use palettes more strategically. The result is to evoke a particular emotion, mood or aesthetic. The RGB color model is one of the most widely used color representation methods in computer graphics. It uses a color coordinate system with three primary colors:

R (red), G (green), B (blue)
