Which pigment should I use for grey, white, black or blue epoxy?

Grey: there is no grey liquid dye, but you can combine the white and black liquid dyes to get a grey tone, and the mica powder line includes several grey options.

White: use the Porcelain White or Snow Queen mica powder.

Black: the Pigmently Dark Matter mica powder gives the deepest, most opaque black with real depth. It's ideal for a rich, solid look and also works well for subtle swirls. The Pigmently Black Liquid Dye gives a clean, single-tone black, but liquid dyes are naturally more translucent, so you may need to add more for a fully solid black. The same two options apply in UltraClear Deep Pour Epoxy.

Blue: there are many blues to choose from. Real Royal Blue and Neon Blue are the standard powders closest to the Sky Blue Glow-in-the-Dark color, and Greek Turquoise Pearl powder or Teal Liquid Dye are other options.

If no single color is right, blend two or more pigments to create a custom shade. Everyone sees color a little differently, so order the 5g size first and test on a small scale before committing to a full pour.
