More color

I finally got the Luvotex- color set I've been waiting for. I just love all the mixing and measuring and counting, reminds me of the days when I studied chemistry. Laboratory work was always my favorite, not the boooring lectures. Only thing that bothers me with the Luvotex is that one is supposed to use a salt with it, but it's not clarified what for a salt that is (it's not NaCl, that they tell you). It's doesn't really matter, but I'm just really curious. I bet they don't tell, because it's cheaper elsewhere (plus it's not really necessary every time you dye, depends on what effect are you aiming for).
