Yes, I know!
I think I did not explained well (sorry for my english :( ).
My idea is to use the similar (or same) color for the background wallpaper both
for playmouth, kdm and kde (i.e.: like in Ubuntu.).
A simple example is to change the kdm and kde wallpapers with colors similar to
playmouth
Cant do unfortunately. Plymouth on some drivers only supports 16bit
colors, the kde artwork looks crappy at 16bit though :(
