Using food dye we made "Christmas Crack" - red and green rocks ... but color doesn't mean much - MOST crack is not white but the light-tan/yellowish we are used to.. still, it all depends on what you start with, how you cook it, etc...
Again, and this applies to ALL DRUGS - COLOR DOES NOT MATTER! The Blue ecstasy pills are not always going to be better then the Pink ecstasy pills... the TAN heroin is not always worsethen the WHITE heroin... same with coke/crack..

"I am not one of those weak-spirited, sappy Americans who want to be liked by all the people around them. I don't care if people hate my guts; I assume most of them do. The important question is: 'What are they in a position to do about it?'" (William S. Burroughs)
