I was looking for a long time for a yellow duvet cover that had a good design and the right shade of yellow, so I'm happy to have finally found it here - and at a good price!  This duvet cover set is reversible, and I only use the side with the geometric shape pattern, which is the side with the zipper and pillow case opening.  This doesn't give it the smooth, seamless look that I like.  If I had known that, I would have gone with a different option.  But otherwise, I am happy with the quality and how it looks on my bed.
