Yes, you can color ComposiMold. You can color it with food coloring, color pigments, and color powders…pretty much anything.

ComposiMold-Original (or ComposiMold-Used) has a yellow tint to it, so colors will be skewed towards the yellow spectrum.

ComposiMold-Flex is more transparent with less yellow in it, so it will create a more true color. Flex is more flexible, rubbery compared to the Original.

With food colorants, you can still have a slightly transparent ComposiMold and can make a beautiful blue, green, yellow, and red. Or black. White might be a challenge with food colorants. Use up to 3% by weight of the liquid colorants in the ComposiMold.

If you want opaque colors, add dry pigments up to 5% by weight into the ComposiMold.

For white:

We tried a few different fillers to see what would give the whitest opaque color. We tried our white colorant (https://composimoldstore.com/resin-colorants-select-the-colors-you-want/, plaster powder, baby powder, and titanium dioxide. You can add pretty much any powder filler to the ComposiMold.

The best I found to make an opaque white was the titanium dioxide powder (here’s an example from amazon: (https://amzn.to/40wVSgZ ). It’s very marshmallow-y white, but not quite as white as a piece of paper (see image below). I’m sure a zinc oxide would also work just as well.

Our white epoxy pigment also made it white, but it was more off-white with a touch of tan. And it turns out baby powder, plaster, and flour aren’t really as white they appear compared to titanium dioxide. (Although I think of them as white).
