Have you read the Palette Manager manual?
If you want to draw an image with certain colors, create a palette with
those colors, and them use PmForeColor to set the color (you'll be setting
a number corresponding to the palette position of your RGB color), and then
use LineTo or something (this is also neat if you have run length encoded
image data - if you have 10 pixels with the same value, do 1 PmForeColor,
and then a Line to 10 pixels down the line).

Unfortunately, I have no sample code, but good luck anyway.
