light intensity can change the color to a point.you can have yellow,tan,green,red,purple.if you want more than one color you need more than one kind of live rock cause in nature you don't usually get different kinds intermixed on the same rock.thats why its nice to get differnt kinds of rock mixed together to get several colors
