NASA has been showing photos with a red shift, so much so that one
photo with the NASA logo, the logo was a ruddy red instead of blue!
Seems they think the public should see a red martian sky, it's
actually a pale blue. Kinda like ours on a very very humid day except
maybe a bit darker. At least thats what I recall years ago from
Viking and Pathfinder photo's.
That's incorrect. The Martian sky is actually red and not blue. The
mistake was made when the very first photos from Mars were received
years ago and were grey scale. The engineers who colourised them got it
wrong and added too much blue to make the sky seem familiar but wondered
why the landscape had an odd colour. These incorrect photos were
released to the public but the mistake was picked up within a day and
the correct colouring was released the next day. The only time the
Martian sky is blue is at sunset so it's the opposite to what we're
familiar with. Even professional astronomers process photos through
Adobe Photoshop to enhance the colours. All this info was in an issue of
New Scientist magazine some time ago.

That, I think, was an old theory. The scientists now prettyy much
agree that the sky is blue even mid day since color corrected images
have shown this to be so. There is a red tinge and it can turn
completly red depending on the amount of dust in the air. However the
Nasa logo should definately be blue, not red. See the following link.
