Posted: There have been extensive discussions on this before but to simplify, here are the gists of what was said before.
Generally speaking, Meths is the most widely available fuel that will "suspend" chemicals into it. Yes the flame can be weaker but, larger wicks can counteract that.
Using wicks that have had Kero/Parafin on them are sooty and have heaps of Sodium compounds on them. Consider this the Orange Flame Chemical. It's orange colouring effect is more powerful than practically all the other ones. That's right, it's not just Boric acid. All the colours are theoretically available. There is an annoying tradition on this bord for phantoms to post that they got 4 colours to work then disappear without saying how.
Make new sets of wicks for each colour you want. Use well attached natural fibre alternatives if you can't afford to buy more kevlar.
Try the dissolve-in-water-then-dry-out technique. Make a super solution of your chemical in water then utterly drench your wicks in it let it dry out to "seed" it. Works best if you put the wick in unrolled bfore you attach it to heads, then let them sit in the liquid while it dries out.
Get pure chemical compounds or not at all. Potassium Chloride should burn purple and it's widely available as a diet salt to reduce sodium in your diet. But this product contains heaps of sodium, the orange chemical which overpowers totally... Read the ingredients, look for "100%"
IMPORTANT: If you are going to attempt these effects, now is the time to get into MSDS sheets. There is an article on this site and there are many other directories on the net. You need to understand the dangers and be able to apply what's on these sheets. Look for what Decomposition Products relate to the chemical used, because these will include what you will be exposed to when you burn them.
Where to get. The blessed few are Uni students with lab access. You bastards! Oh I'll just pick up some Lithium Chloride to make a wicked scarlet flame. Here are some more ideas but be sensible and promise me you will learn the language of MSDS first. Fireworks suppliers Pigment suppliers hardware suppliers food additives suppliers (maybe!) Fireworks is interesting because we all know that every colour has been done by them every day, but most of the compounds used are impractical for twirling, like phosphorous with it's beautiful intense white light and sun-like temperature. Scarily enough they use some of worst chemicals, which then settle on whatever underneath.
OH, and when searching this board, spell coloured both ways so you don't just get americans

Posted: as a further note you have to remember that boric acid will only dissolve in a solvent that is POLAR!! your petroleum distillates are not polar so your boric acid wont mix, at all, it will coagulate down at the bottem and not even effect your burn, the sodium content is also very high in petrol, because it burns hotter its what they put into fuels to get better effeciancy, this is why you should use aviation grade kero, or ultra pure lamp oil (next best thing) and if your going to do extensive colours, have a different pair of wicks for each colour, and label your wicks so you dont contaminate your chemicals all you need is a little bit of sodium, and your darker reds and purples just wont show up, the sodium will completely overpower the hue that you are trying to acheive anyways keep it coming people, this is becoming an definitive thread

Posted: ok this might be a stupid question but i have been reading through this thread and nowhere does anyone talk about mixing any chemical with kerosene to get different colored flames. is there something about kerosene that doesn't let it react well with other chemicals? would kerosene be ok to use for different colored flames? just thought i would ask.

Posted: it was discussed earlier in the thread kerosene and other heavy carbon chains, (aka petroleum based fuels) are non polar the boric acid is polar like most acids, so its not miscible w\ a non polar solvent so your boric acid would be your solute the kero your solvent since the boric is polar and the kero is nonpolar, they wont mix, so you wont get an even dispersion of the boric acid on your wicks so.......no green also if you get pure jet fuel, it may or may not have sodium added into the mix to make it burn at a higher temperature and give the jet greater efficiancy...so the whole issue here is trying to find a fuel w\o sodium, and that is also a polar solvent last but definately not least, is finding a fuel that fits these criteria that isnt toxic
