I'm thinking two sensors. One specialized for monochrome, the other for color; best of both. To avoid distracting the user, it wouldn't change mode with shifts of illumination, until the user hit a button. There might be a little blinking green light at the corner of the eyepiece to indicate the illumination is sufficient for color, and a red one to advise switching back to monochrome.

There could be applications where that system would be the best possible way to go. Keep in mind the likely downsides though: weight, cost, power consumption, size. These can be minimized, but not ignored.
