A classic FAQ. Check out David Fanning's website www.dfanning.com.
While there, you may want to check out this:
http://www.dfanning.com/color_tips/colors24.html
I recommend his book. It is well worth it and you won't feel so guilty
using all of his code :)
You may also want to consider running your X server in 8-bit mode.

device, decomposed=1 (this should be by default)
!p.background='ffffff'x (for a white background)
!p.color=0 (for drawings in black)
