Fireplace crystals change the color of a flame because of their chemistry of combustion. The crystals have different chemical compounds in them, and each compound gives off a certain color light when it is burned. You experience the wonderful effects of this every year when you watch fireworks. The people who make fireworks know (just as do the people who make fireplace crystals) what chemical compounds will burn with a bright red flame, what ones make the brilliant blues and which the superb greens.
