Love the feel of the fabric and the colour. I wanted silver or a light grey. One reviewer said that on her window they looked grey green so I emailed Wayfair to ask. They checked with the supplier and promptly got back to me advising they were a true silver but may appear different depending on lightingwindow direction etc. I took a chance and ordered ..received and very pleased they look true silver in my space. Cant speak to the room darkening quality as they are on my patio door not bedroom. They were described as thermal..but no thermal backing or liner so Im not sure how effective they will be in winter. Overall very happy, they look gorgeous.
