From left to right: original image, after applying MaxRGB filter
You can find this filter through
Filters->Colors->Max RGB.
For every pixel of the image, this filter holds the channel with the
maximal / minimal intensity. The result is an image with only three
colors, red, green and blue, and possibly pure gray.

Parameter Settings
Hold the maximal channels: For every pixel,
the filter keeps intensity of the RGB color channel which has
the maximal intensity and reduces other both to zero. For
example: 220, 158, 175 max--> 220, 0, 0. If two channels have
same intensity, both are held: 210, 54, 210 max--> 210, 0, 210.
Hold the minimal channels: For every pixel,
the filter keeps intensity of the RGB color channel which has
the minimal intensity and reduce both others to zero. For
example: 220, 158, 175 min--> 0, 158, 0. If two minimal
channels have same intensity, both are held: 210, 54, 54
min--> 0, 54, 54.
Grey levels are not changed since light intensity is the same in
all three channels.
