Speaking about colors, notice von Braun's blue skies, with no dust.

As far as image manipulation goes, I don't mind either blue skies, which duplicate field conditions on Earth, or white skies, which duplicate lab conditions. Both are legitimate scientific techniques.

But given the wide-spread delusions some people hold about Mars, I do mind when NASA does not identify the images as manipulated, and clearly state why that manipulation was done.

What does NASA hide when it does this? The real Mars.

Notice the impact debris littered about the surface. Notice that the larger chunks of this debris are grey, and that when the layer below the immediate surface is disturbed, the sub-surface is grey as well.

Note that the immediate surface of Mars consists of dust from iron asteroid impactors, and that actually Mars resembles the Moon under that top layer, and not the US desert South West.
