I thought I would post the steps from the original image to my truer colour version.
Left: the original data as initially presented here

Middle: the results of laborious hand retouching on each colour channel to remove the light leaks which mar the performance of this otherwise excellent color camera. The violet channel in particular is horribly lightstruck to varying degrees in nearly all such images. Constant comparison with the original was done to minimize subjective retouching effects. The result attempts to emphasize the colour subtlties of the subject the camera is seeing and minimize the ideosynchrosies of the camera itself.

Right, the results of rebalancing the colour to resemble known ranges of Martian hues. This image was widely distributed. More image releases using this technique are forthcoming.
