    Item was a slight shade lighter than the pattern listed. Evidently, it was a pattern that was identical and very close to the color of the one listed. Totally, hard to tell unless the colors are side by side. Seller kindly helped me figure out that it was not the pattern I was looking for. And very graciously offered free return shipping and reimbursement. Great communicator and highly recommend this seller.
