Thanks for starting this thread - it's so much fun to see and share ideas like this!
One of the reasons we fell in love with our home in TV (aside from the beautiful pond and golf view) was how the interior was painted. Believe it or not, the colors matched our furniture from home, so Mr. Travel was thrilled that he did not even have to paint one wall! I've attached some pictures below - I love that one wall in each room is painted a lively color and the other three are neutral. Just enough, and if you change your mind, you only need to paint one wall!
