Can you dye casting resin with food dye?

Answer 1

i don't know, but it sounds like you are looking for a cheap way to do it, so i would use kool ade powder....its a starting point.

Answer 2

I wouldn't use anything water based (you might possibly be able to get away with using just a little though).

The special colorants sold for coloring resins are basically artists' oil paints (in tubes) though, so you might want to buy a small kit of colors and use those.

There's more info on coloring resins on this page if you're interested:

(I'm pretty sure the category called "Coloring" that's under the Epoxy Resins category would apply to polyester/casting resins as well)

Answer 3

It isn't recommended, but you could try it and see if the results are what you wanted. You would be better of just buying the transparent dyes make just for cast resin.
