I don't think the gold/silver colour is anything to do with eating minerals. The MH community is obsessed with monsters eating rock, but there are very few animals that eat from the ground. Only example I can think of is elephants eating rock salt.

DNA is one of, if not the, densest form of information storage known to man. I see no reason why having 3 colours would be a problem.
