Nissan Z Proto in (almost) all the colours of the rainbow

UPDATE: The fans over at 400ZClub.com (gee, they've really doubled down on the 400Z name!) have created a set of nicely re-coloured examples of the Z Proto, so we've added them to the story below. September 17: The very special new Nissan Z Proto concept was revealed today, showcased in an especially bright yellow that not only paid tribute to the 240Z and 300ZX that inspired it, but also got tongues wagging.
