Do you want to go lighter? The Van Deusen Blue is very very dark! I would look at Gray Owl, Smokestack Gray, Edgewood Gray, Blue Springs. Don't rush into a paint decision though.

Warning: (learning from just painting Grey in my living room that has loads of windows and light) Most Grey colors turn out much darker looking once you paint them on all the walls. We spent $2,000 to change the grey in our livingroom to a lighter grey because the first one turned out too dark and that was a grey that was much lighter than any you have choosen. I had even gotten a sample and painted one wall to test the color but when the walls all reflect off each other it gets way darker! I would test Beacon Grey or Breath of Fresh Air.

We ended up using SW 7071 Grey Screen You can see in this photo how much darker it can get depending on the shadows and lighting.

Here it is in the day light:

During the day it is almost baby blue but at night it is VERY grey.

In a room that gets limited light sometimes it's best to embrace that and go with a dark color. Offices can handle darker more dramatic colors than more public living spaces. Don't rely on the paint to bring light to the room.

If you do want to go lighter though you can always cut the paint color with some white. Also look into BM Silver Grey, BM Smoke and BM Silver Mist.

Thank you all! Jaime - that is a massive difference between night and day. Craziness. Thank you for sharing though as it is very helpful.

mark - smokestack gray is gorgeous. It's even darker than Van Courtland blue but similar.

I am going to steer you away from blue to more of a a green undertone and suggest B.M. Horizon. Paired with lots of white it will be perfect for an interior room.
