I have tried various gs devices and even downgraded gs to an old version
with no improvement.

However, if I set the %newimage option "-colors" to some insane value (-1 or
500000), the foreground color is indeed used for the image (though the
background color is slightly modified).

I still have to check, whether "%newimage -colors -1" also works on the
system that did not show the original problem. If yes, that would be a workaround
for the moment.
