Ok not to argue but when most people buy candles it is for the color and then the scent, to make sure it matches there decor and of course smells good. Me on the other hand I really dont care what color it is as long as it smells good. But I wouldnt expect the candle to change colors that bad after I light it. If it is really ugly I will try that FO from a different supplier(s), and if that didnt work I would not sell that FO. Now this is just my opinion, and I am sorry if you dont agree but I feel you should be confident and feel proud of your creation. I mean really how would you feel if you had customers bring it back to you saying "this candle turned into a really ugly color". I mean are you going to tell the truth and say "you already knew that but that is how it is", or are you going to lie and say "I wonder why I did that". As a side note you could call that FO a color changing candle. Also When I was working with 100% soy candles if my wick was to hot I would get this white ring in the middle of the melt pool, it looked like the color just disappeared out of that part of the wax. Maybe try wicking down a few just to see if that will help out any, and still get good burn results.
