That really, really doesn't look like the same colour as the C207 (I think) the OP posted. Neither do any of the Indium Grey Metallic cars I've found pictures of on the internet. On the other hand, all the Pearl Beige Metallic ones do.
Now if it was Tanzanite, and with a cream interior, it would of course be right up my street....
In direct sunlight (like the photo of my W212) it has a more grey shading; in duller conditions it’s distinctly bronze. Pearl Beige is much lighter - more of a champagne colour.
The only way to be certain about the C207 is to check the paint code, but my money is still on Indium Grey.
