No, No - the point is being missed... (Score 1)

What is important is that blues are mapped to "image" red and greens are mapped to image "orange". This cannot be reversed or colorised to something else since this process is one way. With pictures of stars it is irrevelent since there is far less to see. For instance the jpg images now contain "sky" information in the red band of the image with all the other red spectral data "mixed in" - thus it appear red now. And the green band is now part of the yellow and red ends of the spectra(looks like the dirt. It no longer is part of the green band and is blended with the these other colours. The blue sky and the green "shrubbey" can not be restored since there is now no way to separate the two types of image. Once you scramble an egg you can't unscramble it without the original data. All I can suggest is to use the original Maestro pan images that will be released today and it should have all the data you need... provided that they include the target in the image as well. Lets hope this is not fiddled data and we can finally see what mars looks like. You will have to "do-it-yourself".
