i purchased 4 of these panels (2 sets)  Very nice quality.  They were the vanilla color, nearly white. It's White on White with a pattern of bare trees branches.    They feel thick but they let light in.  I can see my horizontal window blinds through the fabric.  I am using them for their thermal features behind a printed panel.  So I'm paying for their pretty appearance though no one can see them.  I would not expect them to be an effective blackout panel but that is not why I purchased them.  They would make a nice looking panel in a room that had an organic natural feel to it.
