I think this is the only piece of software where effort has specifically spent on making the interface more brown. Is this what Mark Shuttleworth called 'a designer's touch'?
Ubuntu has adopted a not-widely-used colour (probably there are reasons for /that/) and sticks to it consistently (to the dismay of many :). As an effect, many people (who have seen Ubuntu) now associate orange/brown with it. It's simple brand recognition.
(Personally I don't like their choice, but in a world saturated with bluish/lightgrayish/greenish/sunny spring morning colours, it's a brown cow)
