My plan was first of all to let it use datatypes for getting the colors... Then to make notify on Env:Sys/WBPattern.Prefs, so Colorado could be notifyied about the new colormap, and to disable remapping for the new background. But I also wanted to do a Pattern pref for each screen depth, the Pattern pref should then contain WB/Scr/Wind. pattern/picture, which of them should be remapped, and from which it should take the palette, or ofcause "other palette",Then you could choose to have some awesome pictures in 256 colors, and just a lousy pattern in 4 colors... If you would like to realize my dream, please do so, and write me! Also if you have questions about how I would have done it or anything else... Signed
