Coul you try adding a test? This will not work for gtk2 because gtk2 is
different but if you add a test that does something like this -

if (result.foreground.pixel = 0) and ((result.foreground.red <> 0) or
(result.foreground.blue <> 0) or (result.foreground.green <> 0)) then
  if (style <> nil)

it _might_ fix it for when the color already has a valid pixel.

which sounds like in this case it is.
