What you need to read is the Palette Manager chapter in Inside Mac V.
You can assign colors to your palette in a variety of ways, including
"explicit colors" which are colors you refer to by their CLUT index,
not their RGB value. Using this method, you have complete control over
which color tabe entries you use for drawing. This method is only
supported for CLUT devices (of course), so be sure to check the
gDevice flags to determine the nature of your output device.

Hope it helps!
