Explain color theory

Heather's store manager has asked her to arrange some clothing items into pleasing color combinations. As she goes about her task, Heather thinks back to her early school days and remembers how much she enjoyed choosing crayons from the 64-count box. Once again, colors are a part of her work. Heather has an eye for color, but doesn't know exactly why certain colors look good together, so she decides to explore color theory.

Color theory is a set of principles used to create harmonious color combinations pleasing to the eye and senses. It provides us with a common ground for understanding how colors can be used, arranged, coordinated, blended, and related to one another. Color theory is about why some colors work together aesthetically, while others do not. Thus, it's about color mixing and the visual effects of color.
