If BFS looks at the composition of these gems, and I am not convinced they do,  chrome is the mineral that gives rubies their red color. BFS seems to base the combos on more overt characteristics of the gems so far snow and white, forms in seawater. The crystal connection for emerald makes sense, but lichen is barely green and in fact has other colors. How they decide on the combo is a mystery to me. My predictions have been wildly wrong since I like a scientific approach.
