I do know there are chemicals that would probably be able to turn your flames tye dye but, they are expensive and, I don't think the flames in " 2 Fast 2 Furuios " were real ither, you know how many science and math formula's it would take to get a pink flame, I wouldn't be able to do it and, you would have to try each color formula to get the color you want. With the money the movie companies have, they probably edited those flames or put them there.
