Nice looking shelves. Yellow is a mustard color. It was a great color for my boys bedroom. It is a very big unit which we like. I am rating it a 4 versus a 5 because the packaging seemed to have been compromised. The stickers that cover the holes were floating around and affected the strength of stickers. Also in building the shelves the instructions were a bit unclear- for example, it does not specify front versus back of shelf which caused us to need to rebuild the unit as it was initially built (following the directions) backwards. We fear that rebuilding it has caused it to not be as sturdystable.
