A few dealers (maybe all) in Europe have been able to get their mitts on a two page brochure with photos of the new MINI, and samples (examples) of the interior finishes and exterior paints.
Here is a scan of the exterior paint samples. The colours etc are "as scanned", and look pretty much like the real thing to me.

Lightning Blue actually looks a little purple in the brochure, which makes me more keen on Laser Blue.
