Synthesized color image of Victoria Crater cliff on Mars from Opportunity
I took three images from the raw frames available on JPL's Mars Rover web site and created a color image. They are not the fully correct colors: I used the "near-IR" (750nm) filter for red, green for green, and the UV (or short-pass 430nm) filter for blue. Opportunity Color filter IDs are from Mars Rover Pancam Filter Specs. I sharpened the image and slightly reduced the cyan content. Colors are, as you should always suspect, suspect. Click on the image above to get the full 1024x1024 image.

Cabo Frio, as the cliff is now called, as synthesized by JPL: http://photojournal.jpl.nasa.gov/catalog/PIA08806
And make sure to see the Victoria Crater panorama in great color here.
Why is the sky so blue? It looks like earth. All of the other photos I see form mars are orange.
The 'blue' in this image was actually the UV filter, and the 'red' was actually near-infrared. This can skew the color significantly. I even removed some of the overwhelmingly cyan cast from the image. The sky of Mars does in fact look orangish during midday because of all the dust in the atmosphere.
I made another mars color image here.
