I bought, many years ago, from Brownells a box of glass jars with the different pigments in it. A tiny amount on a toothpick is all you need . I mix the pigment in as I stir the two parts of the Acraglass gel together. I have a question, I am using more epoxy with a grey colour, with a small amount of hardener about 20:1, can this marine expoxy be coloured as can Acraglass Gel?
