In the beautiful village of Auvillar, there is an economical use of color. Shutters do not exist in every hue of the rainbow. Doors or windows either. The world of color in the paint department is finite. Go wild with your flowers, mais faites attention! with the paint. Some of us have theorized that paint colors may be regulated by the village--or perhaps the larger entity that chooses the 1oo plus beaux villages de France. It could be that these colors are traditional and have existed for centuries. I do know that if you rebuild a historic house here, you must find old roof tiles to re-do your roof. In any event, they've made some good color choices. These colors seem drawn from nature--flowers, the stripe of color on a bird's wing or the shell of a beetle.
I live in a condo complex in the L.A. area. We have rules, too. We have a color. One.
