- redefine or create a color
setcolor color red_level green_level blue_level
The setcolor command takes four arguments: color, which must be a string naming the color; and the arguments red_level, green_level, and blue_level, which must be integer values defining, respectively, the intensity of the red, green, and blue components of color. Intensities must be in the range of 0 to 1000. If you are redefining an existing color, you must use its current name (default color names are: black, blue, green, cyan, red, magenta, yellow, and white). setcolor returns the color's name string.
