It is Seal grey.
It is very close to Meteor. But i think meteor is just a little darker.
Although the greys and silvers are considered "boring" by most it still think its awesome.
I felt that Arctic was too "common" and liked the darker seal better. I would have chosen Meteor if i were choosing today.
But Arctic is the classic porsche color and "silver" was the color assigned to the German cars in the Le Mans races from the beginning. As a bonus Arctic is easy to maintain.
Hope this helps.

what color is the car in the pic. I am agonizing over choosing meteor gray over arctic silver...
