In the nursery I used Martha Stewart "Flagstone" from Home Depot.
I recently had someone ask about my bedroom. I used Glidden "China Rain," but it was a couple years ago when I painted so I'm not sure if they still have that color available.
The living room was a color I found while I was still in school in a really old Benjamin Moore swatch book that was in our sample library. I think the date on it was from sometime in the 80's. Anyway, the paint swatch only had a number on the back so I never new the name. I had Columbia match it. Well, just a couple weeks ago I stumbled upon the swatch and guess what! I just googled the number, and Benjamin Moore still carries the paint color!! It's called Antique Pewter. Just to warn you, it has a lot more green in it than it looks here in the picture. The color changes a lot with light. During the day with more natural light it looks more gray, but at night with my interior lights on it looks more green.
My kitchen paint color is Ralph Lauren - Old Violin, but I had it matched in Behr paint.
There you have it! And thanks for the questions. I love that people are stumbling upon my blog.
