Use Alumilite Dye to colour your casting resin. These vividly coloured liquid resin dyes are translucent when used in clear resin (Amazing Clear Cast), and opaque when used in white or coloured resins (Amazing Casting Resin). Alumilite Dyes are used with resin to give an even and complete colour, with a reacting pigment dye that will never leach. Add the dye to the "A" side of the resin by weight up to 5% to achieve the colour and tint you desire. One drop goes far!
