It's magic! Seriously, it's the magic of Del Sol's proprietary Spectrachrome® Technology. Spectrachrome crystals reveal their hidden colors when exposed to sunlight. NASA invented it for their space program, and Del Sol enhanced it for everyone under the sun! It's not rocket science, but then again, maybe it is.
