The better question is what can you NOT breed to a pastel. The pastel in my oppinion is the best morph ever produced by nature. It makes everything better. I dont think there is anything you cant breed a pastel to. Now with that said the question you need to answer next is how much money you want to spend on a male. Calicos are hot with pastels, fires are hot with them as well. Lemon blasts another good pickup. The combos are endless. My pastel girls every season are the hardest for me to decide on how im gonna breed them. This year im putting them in the mix for sterlings and silvers, pastel calicos, blast projects, and citrus stuff
