Hiya M.R.

NASA's explanation for disparities in colour is that they are combining photo's taken in green blue and 'infra-red', not true red - as this shows up which rocks are free from dust, making them good targets for samples.

I'd have thought that would make blue objects appear black, but that's what NASA say and I'm no expert so who am I to argue?
