One thing that could be done by changing the colors is to make it easier to differentiate tissues. E.g., you play around with the colors to maximize the contrast between normal and damaged/cancerous/whatever tissue and start cutting away the bad stuff.

Note: "could be done". Don't know if this is actually done. Even though dermatologists, for example, do something like this during skin examinations.
