I tried red pigment for resin and if you want to make the resin become completely red with no refrection you have to use more pigment..but great result I used red one and it was perfect

Contrasting colours are best as it allows you to see the defects easier.  You can also use different shades for different layers to help you see when you have sanded through the top layer to the next.

Actually I've just found your White Epoxy Colour Pigment... didn't look too hard first time!

Hello -- is it possible to colour your Coating Resin?
I would like to give it a colour (preferably white) as it's easier to see contours for sanding than if it's clear.

Many thanks,
