Consider painting or purchasing the tiles with paint, as they do look like styrofoam on a lower ceiling.

So easy and fast! Looks beautiful! I've used your styrofoam tiles in two rooms now. One of the best remodeling decisions i have made.

Quality of the tiles needs to be improved. Many tiles had sides with bulges in the middle, which forces you to constantly rotate the tiles to keep a somewhat straight line. I didn't like the taking the tiles all of the way to the edge of the ceiling, it left a lot of holes to be caulked.

Easy to install. I found that you need to put more adhesive on back. It holds better.
