I can see how upgrading to a 256 color palette might be useful. But beyond that there's no point. The eye can hardly distinguish those 256 as 256 different colors. The difference between colors would be too small to be useful.

PS: I know mIRC has the ability to let you define your own palette, don't know if that is limited to 16 colors tho...
