If any of you out there are Ubuntu fans like me, you'll be over the moon to read Jono Bacon's announcement about Ubuntu's rebranding! Here's the short version: the colour palette has shifted from brown with orange accents to a lovely aubergine with orange accents, and the whole visual style has been designed around the theme "light". Some hardcore Ubuntu-ites are already crying out for the loss of their beloved brown, but I for one see the change as welcome, and the look overall is more professional and polished than before. The new colours and style make Ubuntu look sleek and modern, and will help promote its position as one of the "big" mainstream operating systems.
Here are a few shots from the branding wiki page (which at the time of posting was only intermittently available, due to "technical constraints or capacity issues"!):
Well done to Jono and the team!
