I looked at all of the color selections before I decided on gray. I THOUGHT I was either getting multiple shades of gray, or a light gray. I got a dark color. My husband and I tried multiple lay out designs to try to show off the panels, but they are too dark. The wall looked like I painted it black. The panels themselves are nice wood pieces. There are wood grains and knots visible.  The adhesive is strong and dependable. If I had a lighter color, my wall could be covered. I'm not going to use these dark panels alone. I gave them 3 stars because the manufacturer misled me with the pictures they provided to show colors. If you can figure out the colors, these panels would provide a nice rustic look to wherever you put them. I'm disappointed I can't use them.
