As epoxy's bond to wood is stronger than paint, you will have a weaker hull by painting first.

Fiberglass boats (with polyester resin) have a pigment added to the last coat (gel coat) to get the desired color. My fiberglass supply store sells pigments. I don't kow how well this works with epoxy resin but there must be lots out there that have tried it.

I suspect that as your last (flood coat) of epoxy would be sanded to get the hull smooth and then the color coat would be an additional coat, more weight and more cost. Paint is cheaper to apply and repair than epoxy and has less weight.
