If you point at the NASA logo on the rover you will see how big the color shift is. It's supposed to be blue but it's yellow and red. Whether it's the lighting on Mars, or the camera, or post-processing to blame for this - I have no idea, but the picture doesn't look like it reflects the reality from the human eye's perspective.
The OP's interactive panorama is extremely cool, but I prefer the original you linked here. With the color shift and distortion, the interactive one feels dreamy and imaginary. The original is just so raw, real, and powerful. It makes me think "holy shit, this thing is on another planet, and it looks a lot like our own!" I can almost imagine standing next to the rover, surveying the desolate, alien landscape.
