My digital camera doesnt perfectly match the hues I see, and that camera has MANY years of research and hundreds of millions of dollars invested in it to ensure that it matches the human eye. The spectral response of the human eye can be roughly approximated by a gaussian centered at 550 nmand droppin effectively to zero at 390 nm(blue side) and 780 nm (red side). Unless you perfectly match that response you are not going to get a 'true color' . The camera on the rover uses several filters so the reconstructed image is from several images each with a different spectral response- That is not going to give a perfect recreation of what the human eye sees...
Additionally, the human eye spectral response curve varies slightly from person to person- For instance, several years ago I found out that my eyes apparently see further into the UV than average (something that changes with age).

- Oh, and here is an unrelated fact about the eye that I bet no one here will believe:
- Does that mean you would be happy with a digital camera that changed a blue NASA logo into red? (n/t)
- Gee, Bob- maybe they are busy doing real science?
