**Reiny**, Tuesday, January 22, 2013 at 8:33amSince it asks for "how many different combinations of the colours are possible"

we are merely interested in the number of subsets of the 4 colours.

number of subsets are 2^4 = 16

but that would include the one case of not choosing any, so

I would say there are 15 choices of colours

The answer would be the same if there were 200 tiles, as long as we have some of each of the colours
