Epoxy/eps buckle repair

I’m going to repair an epoxy eps board that buckled on the deck and I want to try to color match the existing color which is under the glass. My plan is to remove the buckled glass, feather in the filler, paint it then glass the patches with epoxy. My question is what type of paint to use?

Thank you in advance!

Use a waterbased paint, like acrylic artist’s paint.
