Oh no, then Xdefaults is not involved - cccccc is light gray,
not black. I don't remember if you compiled Prima from scratch,
but I'd suggest to recompile, and add debug information in
apc_gp_clear() and apc_gp_bar(), that are apparently the culprits,
defined in unix/apc_graphics.c , something like

If these will tell that they asked to paint with black indeed, then
there's some color bug in Prima, otherwise it is something else.
