So here are the whites I chose from.
From top to bottom:
-Cloud White
-The Right White
-Buttermilk
-Sand Dollar
With overhead light...
With natural light...
I ended up choosing the bottom color, Sand Dollar by Restoration Hardware. The paint wasn't cheap but I figured I'd be starring at it every day.
And, here is the finished product! Ultimately, I'm pretty happy with it. It gives a nice grey undertone in the shadows. My husband was used to our pretty rich colors so he feels like it's a little sterile but he has grown to love it.
Ok, so I just bought "The Life Changing Magic of Tidying Up" so I can listen in the car. I'll keep you posted on what I think and what progress I make!
Also, they did end up re-grouting Kenzie's bathroom because the beige grout failed. Here you can see the difference between light grout and dark grout with white hexagon tile.
