Even if you decide to keep the wheels, maybe you can contact eas, tell them you wanted BLACK, but you really don't feel like waiting for weeks and weeks again, don't want to go through the hassle of shipping, etc. They might throw you a partial refund or some other sort of reimbursement. You shouldn't have to wait extra weeks just because of their mistake, so if they offer you something for the trouble, you win in the end. And I think anthracite grey would look great on a black car
