Barb, your leaves are looking metallic because they are growing upside down. You are seeing the undersides of the leaves. What are you fertilizing them with? How much or how little water are these plants getting?
I am suspecting that they have been fed a high dose of nitrogen and that is what is causing the blueness of the leaves as well as the roll. It could also be from over/under watering of the plants or a combination of these things.
