if you get just pure natrosol powder what do you colour it with? food colouring is what gyob used but is there stuff to avoid? i assume a colour marked as natural colouring is best.
If you're not eating it, I recommend tempura paints from a dollar store. They are water-based and I've yet to have anything get stained from them. Much cheaper than food coloring.
We use children's poster paint, either powdered or in the liquid form. Its harmless if you get any in your mouth and doesn't stain too badly. Don't use a food colouring as this will stain.
As others have said, poster paint and tempura are best. They're non toxic and won't stain. Food colouring is a terrible idea, unless you want coloured ears for a month after your sesh.
Love you, too
