Nice matte gold paint (one side only, the back of these are black). They are pretty light weight and look nice on just about any color wall. As far as hanging, it’s easy enough, HOWEVER, be careful because the black paint scraped all over my wall as I was trying to find the right spot to hang them. Try not to touch the wall with them, or drag on the wall until you have to. I will end up putting them on another smaller wall or buy another set... I think 3 or 4 of these together would look better than just the two for my purpose, but they are very pretty during daylight and at night.
