The design is inconsistent. If you only use color to signify buttons, making top and bottom banners with the same solid color as buttons is confusing, especially when several buttons are embedded in the top or bottom banner.

That aside, it is a good, clean interface.

Also, way too many people are colorblind to some degree for it ever to be acceptable to only differentiate buttons by just color.
