[2.2.10] Saturation doesn't affect Colormaps in OpenGL

A buddy of mine found a interesting bug with the Saturation Option in Video Settings. If you change the Saturation so the colors are... erm... less colorful or if you want to greyscale everything, however... it seems that this doesn't affect colormaps if in OpenGL.

Console Text is grey'd but the background isn't.

Goop in THZ remains purple-like.

Water remains colorful.

The sunset still applies.

Drop shadows are affected if the shadow is on a slope, this was taken in RVZ1.

Even lasers are colorful.

...and finally, CEZ1 is still colorful while a storm rages.

The Saturation changes are fine in Software.
