What Is Color?

Colors, like features, follow the changes of the emotions. - Pablo Picasso

In 1666, English scientist Sir Isaac Newton discovered that when pure white light passes through a prism, it separates into all of the visible colors. Newton also found that each color is made up of a single wavelength and cannot be separated any further into other colors.

Further experiments demonstrated that light could be combined to form other colors. For example, red light mixed with yellow light creates an orange color. Some colors, such as yellow and purple, cancel each other out when mixed and result in a white light.

If you have ever painted, you have probably noticed how certain colors can be mixed to create other colors. Marion Boddy-Evans, About.com's Guide to Painting, has an excellent overview of color theory basics including how different colors can be mixed.
