Many people have suggested that things like the "Lightsabers" and similar tools blend to your paint colour. Perhaps an option in the Image
and Item datablocks could make them do this.
(Items being to the brick's colour?) I suggest making it happen if the "doColorShift" field in each is set to false - this currently has no use, as you can already make it shift to "1 1 1 1" to appear white and such an option might prevent the need for creating
hundreds of identical datablocks for a single weapon or purpose. For instance, the Paint Cans could change from 256 datablocks (64 x images + particle data + emitters + explosion data) to about two or three.
EDIT: It turns out you can set items to a specific colour by setNodeColor. It'd still be useful for weapon images, though.
