Thanks Robert (did I actually say that?)

I've been waiting for that L4 image to have the hole patched.

There are some odd things about that image.

If you use L456, the red bar disappears from the Nasa logo, but if you use L356, both it and the JPL logo are garish red. I tried a blend of (3+4)/2 for the red channel and got a dark purple-red for both the stripe and the JPL letters. Looks like they're the same paint, but it is quite sensitive to the exact red waveband used.

According to my data, both L3 and L4 are "red".

One can go on to fiddle with the colour balance and make the rover look "right" but I'd prefer to see exposure and other info for the frames, and reference to similar shots on Earth before signing off on it...
