Another interesting effect is they sometimes shift the color of distant
mountains under clear conditions. I have always assumed this was due to
reflections off the rock's crystaline surfaces being polarized with a
wavelength dependency. (Dichroism?) It may also be partly just a white light
contrast issue that subjectively looks like a color shift.
This is handy in that the color contrast can sometimes be adjusted to taste.
