I like to use the paraffin baths (the ones that you would find at an upscale spa) The wax peels right off, leaves nothing behind except soft skin, is temp controlled so you can't accidently burn yourself, the paraffin can be re-used (as long as you are only using it on you). To add colour, I like to use the good old Crayola's.. You know, the ones that would melt in your back pocket on a warm summer day? They do not raise the temp at all, and they come in wonderful coulors.......
