Do you have southwestern style decor? Generally the west coast and southwestern style is pastels and white. They will always be in style. Pick what you personally like and don't be afraid of color or what is trendy. It's only paint. Personally, I prefer neutral walls so I can add color or change color with pillows and accessories. Easier and cheaper than painting a room. This is your home and has to reflect you.

Bungalows and subdued Arts & Craft interiors are becoming the next fad (again). William Morris reproduction prices are rising somewhat, already. I think, in part, because most commercials and TV shows are featuring Craftsman architecture (lots of built-ins and natural woodwork).
