Off-line rendering? (Similar to procedural textures in 3D programming
- usually done in a separa thread, at a rate significantly lower than
the main engine frame rate.)
Anyway, with or without off-line rendering, this is not exactly
trivial stuff, if it's going to look nice, especially not if it's
going to be themable.

Store 24 bit images and dither them down to whatever the screen
format is. That's how the majority of games do it, whether they're
2D, 3D, using OpenGL, Direct3D, DirectDraw, Xlib, SDL, svgalib or
whatever - it all works in very similar ways.
