Man, you're right, I don't know what possessed me to assume that all were right-eye images.
But sometimes a mistake can lead on to more interesting things...
Interestingly, the parallax between the two eyes wasn't too bad, from which I'd deduce that they were taken from far away. It's possible with a little skewing to get pretty good registration, though far from perfect. JPL probably has some very good software to geometrically remap images to do a pretty precise job. This is what I was able to do by hand/eye:
The "daisy" maps nearly perfectly, but registration gets progressively worse the farther you get from the center.
But here's the kicker: You can extract the color info you get from this and insert it into one of the mono channel images. You do an HSL combination using H and S from the color image, and L comes from a mono image. For example, if you use the color above with the R7 image, you get this:
I think that that's how the trick was done.
I'll save the philosophical discussion about how far it's possible to stretch the term "approximate true color" for another day....
