color%

A color is an object representing a red-green-blue (RGB) combination of primary colors, and is used to determine drawing colors. Each red, green, or blure component of the color is in the range 0 to 255, inclusive. For example, (0, 0, 0) is black, (255, 255, 255) is white, and (255, 0, 0) is red.

See color-database<%> for infomation about obtaining a color object using a color name.
