Is there any color that is happier than yellow? These Sunflowers just make me smile. Of course, I have a life long obsession with yellow, beginning when my mom let me decorate my own room when I was 10. I picked yellow shag carpet (yes, it was the 70s), gold, green and orange striped wallpaper with yellow daisys scattered across it and a yellow and green striped bedspread. Not even an angst-ridden pre-teen could be depressed in that room. In fact, I think all office buildings should decorate in bright yellow. There would be happier workers everywhere! And much less passive aggressive (or overtly aggressive) behavior. Think about it.
