To celebrate this we were asked to help Yahoo! communicate the change to its employees across Europe. But this had to be more than just a colour change, it had to reconnect Yahoo! people with the spirit that makes the organisation so special.

To do this we built an interactive microsite dedicated to purpleness. It explains the essence of what it means to be purple, reaffirming the Yahoo! values - fun, inventive, human and relevant - and using examples of purple throughout history to bring them to life.

Purple Haze, Purple Rain, Deep Purple (spot the music theme) and even Little Miss Naughty make an appearance.

The site is not just a testament to an important moment in the history of Yahoo! but a place where employees can go to learn about what makes their company so special and the purpleness they need to embrace in their work everyday.
