Sherwin Williams Gauntlet Gray is a great one, especially since you have a lot of light. It'll look beautiful in both daylight and then with lighting at night. It's not cold either, so it'll keep the room feeling warm. It'd be cozy! Have fun!

I love the range of greys offered by Benjamin Moore! Since your bedroom gets a lot of light, go through the greys with cool undertones. Their colour deck numbers range from 2119-70 to 2132-40. This might seem like a wide range of colours, but once you're at the your local BM store, you'll see it's not so bad. Pick up a few colour swatches to bring home. If you'll be keeping your window treatments and/or bedding, match up the greys that you like next to these pieces. When testing your short-list of greys be sure to view them in natural light. Test the colour swatch up against your window and against the floor too. Once you've reached this point, go with gut-feel! And, yes, have fun!
