Helping a friend choose paint right now; he will be doing much of the work himself. Sherwin Williams is convenient, but he has samples of Aura, which seems like very nice pant. However, the two closest Ben Moore stores always seem to be out of stock on what he needs and not very helpful. So, I'm thinking that if Emerald is like Aura, maybe he should go for convenience and use the SW brand. Does anyone have any experience that would allow you to compare Aura to Emerald?
