That's sort of hard without seeing the rest of the kitchen. Our kitchen is SW "Site Gray" with a slightly darker accent (the color name is escaping me right now).

It is much easier to match a colour of paint to a carpet than the other way around. I would suggest if your are redecorating your bedroom from scratch start by finding some bedding you like, consider the furniture, headboard etc. are you keeping them or buying new. Once you have these things in place then select your carpet and finally your paint choice. Don't rush the project and then you will save yourself some frustrating shopping and hopefully avoid some costly mistakes.

I think you will need to test drive a couple of colors you like in your space.

Thanks everyone. There is not a window in the powder room. Vanity is white, tile floor. I have the Sherwin Williams book of colors so I am working hard to find a good gray color. The granite counter is a blue gray which is why I am looking for a cool gray.
