Some incredible images of fine layering in the rocks here, signs off cross bedding too?

What I find curious about those two images is that there is a a color change which trends horizontally between the rocks. But if you look to the right of the lighter colored area where the first RAT was done you see a darker rock. Do they both represent compositional differences in the rocks or is one the effect of weathering?
