I can do this without low-level trickery, but this would mean one or two (fore|backgroundcolor) additional macro(s) per building block (>20) for every graphic style (currently 2; more to come). This makes about 60 stupid little macros..... nope. I think that in some special cases I must do this anyway (where the color is choosen from a combination of states), but most times a general macro will do. I will try to get it run this weekend (have to learn TeX debugging first). But I wouldn't be surprised if this is the easier part of the problem.
