In my opinion, I would not select Tan. I believe that would be out of place.
Black is not on your list.
For me, on my car, I would go with Dark Grey for the originality factor.
But, if grey was not available, I would strongly consider the Maroon.
It could be striking.
Black would be a more subtle look, but I believe the contrast would be nice.
Please post a picture when it is complete, no matter which color you choose.
I'd like to see it .... for selfish reasons.
By the way, 173 is non-Metalic Anthracite. You must mean 172, correct?
