I bought 4 panels for 2 black and white and gray bedrooms. I gave it 4 out of 5 stars because the intensity can easily overpower the room, especially against pale gray walls..... so if you want "pop", you got it! They hang great.  They do diminish the bright sunlight from pouring in, but not a total blackout. I wish they were lined in a light color to match all the other windows across the house, but I suppose I can buy a liner later on.
