Each color in the visible electromagnetic radiation spectrum has its own individual wavelength and frequency. All of the color seen by the human eye consists of a mixture of the three primary colors: red, green, and blue.

This tutorial explores how the primary additive colors can be combined to produce the primary subtractive colors and white light. The default position of the tutorial is three color circles randomly bouncing within the confines of a window. The "manual" button allows the visitor to stop the random bouncing and use the mouse to superimpose the colored circles in any desired position. Use this setting to explore how the various colors can be added together.
