Joe, a low sun angle means increased reddening from atmospheric extinction- look at the shadows in the painting. An astronaut on Mars wouldn't see the same shades and intensities at all times- just as you don't here on earth. A terrestrial example would be a very red sunset seen from an arctic location. Blue & white everywhere, but it all turns deeply red at sundown (or sunup!). Dust & other suspended particulates are the culprits. So, the answers to your questions are: No, and probably not, although I'm sure there is a lot of color processing and contrast stretching of rover images.

Then remember the views Spirit and Opportunity have been sending back. My question: is this NASA artist stuck in some 1950s fantasy about Mars or are we getting paled-out views from the rovers?
