Funny, isn’t it? :D

Both can't be right and neither probably is. This is as much a fudge-job as working with Cassini raw images are.

It says “near” true color. What would lead one to think this isn’t close to natural (other than the usual things that make all images not really true color)?

That's the only full RGB set that's down at the moment, actually. That's why everyone's been working with this view. P.S. That’s the only full RGB set that’s down at the moment, actually.

Calibrated imagery needs to be used to get proper relative filter brightnesses and careful channel mixing due to filter wavelengths used. I was playing around with channels mixes to more-or less match the color image of the terrain released so far (even though that one was based on infrared and violet filters only) and match this image of the DVD: http://i195.photobucket.com/albums/z213/effinglibrarian/phoenix_dvd.jpg In particular, matching the colors of the Phoenix mission insignia.

Also, to me, the USA flag colours look quite wrong in both versions. I suspect however they did use the flag and the probe as a known "standard"... I'd like to know how did that turn out.
