Well finally picked up the new Aero SS today and here's a few photos before you get the full smorgasbord of them from George tomorrow:

As you can see the colour is very much affected by light and how it refracts it, so it can appear to be different colours depending on both how the light catches it, and the intensity of the light.
I'm sure that Georges photos will be more indicative of how it really looks.

Anyway, very many thanks to all at MMC for the outcome with which I am very very pleased.
