While I'm not a fan of pastel, powdery colors in general, I do think that a vibrant pink can be a really happy hue. Maybe it's because it brings to mind spring flowers and Easter chocolate and the end of a long, gray winter.
Aside from flamingos, we tend to think of pink as a floral color, rather than a bird one. There are plenty of red birds, but not many in shades of its lighter, friendlier cousin.
