I've heard that the Japanese used people during WW2 who could see in near
infrared. I don't know how true this claim is. Though there are other
animals, e.g., bees, which can see in portions of the ultraviolet, I've not
heard of any humans who can. I imagine it's possible and others on the list
might have information on this. (Or David can do a search under "human
vision" in a reputable search engine.:)

I've seen IR used to map surface skin temperature, which is supposed to be
useful in a wide range of things, from monitoring blood flow to the progress
of surface tumors. However, I saw this on TV so it might have been an
oversell of the concept.

Add more wetware onto the brain and integrate it.:)
Another technique might be to more broadly map colors so, e.g., that red
covers a wider range than just what we currently perceive as red. You might
miss some details, but with this method, you need not add any fancy new
components onto the brain.
Anyway, it's all purple to me!
