iPhone 5C - Color of the year edition

Had a thought this morning, that it'd be nice if Apple did a limited edition run of Pantones "Color of the year" on the iPhone 5C


2012 was Tangerine Tango
2013 was Emerald
2014 is Radiant Orchid


If they continued to release a 5C model every year, I think it'd be nice! Whatcha think? Excuse my awful photoshopping, was just to give you an idea :)
