The picture does not do it justice, there is an almost metallic gleam to the fabric and it's not a cheap, thin fabric either.  I purchased the 'antique copper' and it's beautiful. The leaf pattern is subtle but so much better than just a solid colour.  Really does block the bright sun when I want to close these on a hot day in the sun room: it kept the room at least ten degrees cooler in the hot afternoon.  I am sure, on those bitter winter nights, these curtains will be equally effective against the cold drafts.
