What I find really peculiar is how the colors after composition and postprocessing are so different from the other images of Earth at http://en.wikipedia.org/wiki/The_Blue_Marble It seems similar to the problem of determining the 'true' color of the Martian sky: http://marsrovers.jpl.nasa.gov/spotlight/spirit/a12_20040128...

They haven't adjusted these to be true colours - the article says the rust colour is an artefact from combining images from the infra-red and the other colour cameras.
