Coloured Resin

I want to use a coloured resin but I think that the best way to achieve this would be to add a coloured pigment to the resin. I couldn't find anyway to order them from in New Zealand but there is a company in the States that sells them in a variety of colours (above) http://www.shopmaninc.com/pigments.html

Terry has some pigments that we can experiment with next week, so if that works we won't have to buy any.
