Hey guys, perhaps this is a silly question, but what causes the GC oil to have that "nuclear green" color? Is it just a dye like in RP? I was just playing with a quart I got and was curious as the green seems to only appear when you look at the oil from certain angles... I wonder if it glows under black light, that would be cool! omg im a freak!
