This is a three dimensional model of color and light as we see it.

The yellow and magenta sides overlap to create red. The yellow and cyan sides overlap to create green. The cyan and magenta sides overlap to create blue.

Or you may say the green and red sides overlap to create yellow. The red and blue sides overlap to create magenta, and the green and blue sides overlap to create cyan.

The overlaping sides of the cube create the mixed colors. "HexiColor"

See also "Hexilight" for the relationship of space, light and color.
