Color wheel- The spectrum bent in a circle
The colors are divided into warm and cool colors.
Cool colors are blue, green, and purple
Warm colors are Red, Orange, Yellow
Cool colors in general will appear to recede, where warm colors will appear to advance.
This theory is based upon that fact that the eye adjusts when focusing on colors of different wavelengths. Red light waves have a longer wavelength than blue ones.
