I showed the resulting color image (color_300dpi.tif) to a friend of mine,
and he quickly figured out that the colors are fixed by interchanging the
blue and red channels and by shifting the red color layer 8 pixels downwards
and the blue layer 8 pixels upwards. The shifting of the channels to be
performed after swapping blue and red channels.

The resulting image can be found here after swapping the channels
and correcting their offset of "color_300dpi.tif":
