Large impact craters rebound from the initial shock, raising deep bedrock to the surface in the central uplift of the crater. Link to this Hirise epic image.
The real, "real" color of Mars or "the so-called Red Planet" will absolutely shock you, if not then you can't be human! Yesterday I just started asking around (as you do) and a guy on another Facebook Group literally left a message and told me "listen my friend, you need to check this video out"? So I went and watched it and wow the scientists at NASA are absolutely 100% using filters on the Mars Curiosity Rover. It's very strange as I was under the assumption that Mars was well, red? Or at least that murky orange color. If we look at the chart below we'll see the exact optics and filters or spectrums as they like to call it on the cameras on the Mars Rover.
A blooming filter wheel? A wheel of colors or the wheel of different spectrums. It's strange because even the ancient Egyptians called it the Red Planet because it does have a reddish hue or a reddish glow to it, even an aura.
So here we have a great video and this will explain everything about Mars and the reason why they use the filters to get the views "they" want and not the views that we want? I mean it's their money and it's their stuff so they obviously get first dibs on things they want to capture? Personally I would love to view it all in real color and without filters but I know they need to do sciencey things and other astronomy doodads.

Martian Archaeology has nailed it. This video is awesome.
The NASA/JPL Photo Journal website is absolutely stunning site.
The above main image has a release note with it and it explains the actual process that the cameras go through which results in the absolutely stunning and very high definition image. the end results are without doubt the best images that have ever come from Mars and beyond the everyday images that could ever be taken here on Earth. The vivid and stunning blues are phenomenal.

The color cameras on NASA's Mars rover Curiosity, including the pair that make up the rover's Mast Camera (Mastcam) instrument, use the same type of Bayer pattern RGB filter as found in typical commercial color cameras. Bayer filtering means that the charge-coupled device (CCD) that detects each pixel of the image is covered with a grid of green, red and blue filters so that the camera gets the three color components of the entire scene in a single exposure.
Electronics inside the camera can then merge the separate sets of color pixels into a single full-color image. Besides the affixed red-green-blue filter grid, the Mastcam cameras also each have an eight-position filter wheel with specialized science filters between the camera optics and the CCD.
The wheel can be rotated to choose one of these narrow-waveband filters, in the visible-light or infrared parts of the spectrum, or no filter at all. Each camera's filter wheel holds six science filters that, between both cameras, can yield images in nine unique wavelengths from the deep blue (445 nanometers) to the short-wave near-infrared (1012 nanometers). One additional science filter in each wheel is specially designed to enable direct imaging of the sun.
