Since you like gray, try Revere Pewter for your walls. It is the most popular gray on Houzz. Below the wainscot, you could go with a darker gray from the same color chip as Revere. It has warm tones and may lean toward green, but you like green, so that may not be an issue. What is your furniture style? What pieces do you have that you will use?

Hi. Thanks for the ideas. I like a more traditional style. That being said, I have twin 6 yr olds and a 12 year old, so I'd like the rooms to be functional, fun and cozy!

ADD SOME COLOR TO THE WALLS after your project is solved! :-)
