The first one is close to Benjamin Moore racoon fur. It is going to look pretty different though depending on how much light is in your particular room.

I have long loved this bathroom, which is painted in Farrow and Ball off black. Check out other Farrow and Ball blues here. They have a lot of blue blacks as well as blues that look more like your second picture.

SW Moscow Midnight is a deep blue that might give you the look you’re going for. Love the whole idea of this bathroom.

Thanks so much, both! much appreciated!
