RGB SHADES
It sounds like you've got the right idea already, Michael. Go into
AApro (or Animator) and set up the pallette any way you like it. Save
it out and use it as a custom pallette. 3DS will render the 8-bit
flic or .gif with only these colors. You could also take an existing
flc/fli and force it to a new pallette of your choosing with the One
Pallette command. Hope this is helpful.
