The Zune Store has added new colors to the original lineup of Zune HD devices. Where previously, Zune HDs only came in black, blue, red, green, and platinum, you can now order Zunes in purple and magenta, too. Having launched on December 1st, these new colors are available for both the 16 GB and 32 GB models and are at no extra change.
Sadly, enthusiasts who reminisce about the brown Zunes of days past are still out of luck. Brown is not an option and there are no plans to bring it back.
