    What have you used for color-dye when mixing epoxy to match a color?

    Something that doesn't affect the chemical composition of the epoxy....

    I use Moser's Aniline Dye. It comes in powdered form, and is made to be mixed with a solvent to make up stains for woodworking. Three types are available, Water-Based, Alcohol-Based, and Oil-Based. The Alcohol-Based version is the one you want for epoxy. Just put the powder right in the epoxy resin, either before or after you add the hardener. Only a small amount is needed, less than 5% for a solid opaque.

    I haven't tried Mixol pigments, but they probably would work fine. In general, use dyes and pigments that are made to be mixed with alcohol, not water-based types.

    any pigment added to resin will slightly decrease it's strength
