I suspect that in various versions of GD, you may have troubles
switching from a GIF (256 color pallette) to TrueColor (millions of
colors) and back again...

GD may well attempt to anti-alias, de-speckle, or who knows what in
either of those transitions.

I would suggest that you create images with the pallette[s] you want,
and see if you get more consistent results.
