Yes, it's true. The colors of nearly all Mars images are altered. Curiosity uses filters on its cameras, for its own purposes as well as for us..
Your phone does too, and likely every digital camera you've ever touched. They have to, so that you can comprehend what you're seeing. CCD and CMOS sensors see IR natively.
