--- Comment #19 from Thomas Freitag <Thomas.Freitag at alfa.de> ---
It seems to be the colorspace handling and there the lcms integration:
The missing or red painted elements should all be painted in the separation
colorspace "pantone warm gray 7 c". "pantone warm gray 7 c" itself is an icc
based colorspace with lab values input.
So we start i.e. with a color value of 0xff. This is transformed by the
separation colorspace to the lab values (58.8, 3, 6), which still seems to be
okay, but the transformation used on the icc based colorspace transforms it to
rgb value (255,0,0) which is pure red.
Can't really figure out why this happens.
