Here's a recently released Spirit image:
Judging from the color of the mirrors at the sides of the circle around the sundial, the sky looks orange to a tan color. I'm surprised that you can see the surface in this image with the sundial. I was told the field of view of the camera is too small to allow that.
See for example this image:
Note that in the high Sun image, judging by the mirrors, the sky is not red here. I would guess a dark grey, perhaps with a dark blue to dark purple component. The mirrors in the low Sun image do look rather orange. Note also the surrounding circle with the mirrors (the part that says "Two worlds One Sun") rather follows the color of the mirror.
Because of the color of the mirrors I was going to say the first image above was taken during low Sun. But look at the shadow of the post. This shows it was taken during high Sun.
I would be interested to find out why the two high Sun images wound up with different colors, and in fact the first image above looks more like the low Sun case.
