ColorTable with more than 256 colors?

[DarthPaul]

How can you create a color table that supports more than 256 colors?

I've searched through the forums and I've read that I might be able to do this with dependent textures. Could someone explain a little more on how I could do this?

Hmm: I will take a quick guess.

In a pixel shader,
use texture stage zero's R and G channels as texture coordinates (scaled to range [0..1]
for texture stage one.

I guess I should clarify a little more,

tex stage 0 = indexed texture stored as
RGBA.
R/G = tex coords for stage 1
B/A = not used (use for
something else?)

tex stage 1 = palette texture
(up to 64K [256x256]
palette entries )
