That's a very nice image. I believe it when they say that the colors have been carefully calibrated, because Hubble has a couple of dozen narrow-pass filters to give precise color references. That's an accurate rendition of what Mars really looks like, I'd say.
The crater Schiaparelli is prominent in the center of the image, which got me to wondering what Giovanni and Percival would have described if they'd had Hubble-quality telescopes. Maybe there would still have been Martians, but they'd have had a fetish for large circular reservoirs instead of canali...
