I painted my Armstrong ceiling black.
The wall moldings & main beams were painted before I installed them, then I connected the 2 and 4 feet cross sections and painted them when they were up.
I used the same flat black paint on the grid and the tiles, and it matches really good.
I picked a tile that didn't have any grooves in it, called Pebblebrook. I think it was about 90 cents / sq ft. ($60 for a box of 16). For the room, 14x13, the tiles cost about $180.Looks like Vitod and I picked the same color scheme.
