if you dont have a pair of wicks you plan to dedicate exclusively to color, i wouldnt recommend it. a friend of mine lit up virgin wicks with another friends color dye who neglected to mention that it stains the kevlar. now whenever she burns her fans, midway thru the burn two or three of the wicks turn green without notice while the others stay regular. she cant get the dye out. not to mention the overall life of the wick is dramtically shortened due to the corosive nature of the chemicals. you cant use white gas (well you can but it wont work well) so you need to get ethanol-based fuel which is harder to find and very dangerous to work with. so your choices are to carry another fuel along with your lamp oil or white gas or premix your color fuel which needs to be stored in plastic as it is corrosive to metal. some people make it work but personally its just a whole can of worms that im not too interested in opening. it can look cool but people should take into account how much extra work (and money) it is to get adequate results
