decorating dilemma...

So we moved into our house over last Labor Day weekend.. which makes us homeowners for all of about 9 months.

I originally painted it a color called "Caponata" from Benjamin Moore, which I fell in love with in the Pottery Barn catalog. Now I think it's too bold for for my taste as I tend to be more muted and use calming colors.
