And please keep in mind, that there are also some other output devices (e.g. 
the dxr3-plugin) which couldn't handle more colors. And don't ask me how much 
colors the DXR3 could handle. The palette has 16 entries, so this is the 
maximum, but they could only be used if the colors are not too heavily mixed 
together because the DXR3-plugin has to search for reagions with 4 colors 
max. and the numbers of such regions are limited.

Greetings
Stefan.
