I can tell you it looks Greyish-blackish, but I can't say WHICH Grey it is. After googling it, it looks a bit dark to be Palteaux Grey, but again, I don't know my colors that well.
@@Thomas_Everman my McLaren GT is Plateaux Grey (and I used to live with it in Houston!) but this doesn't look like it. Even with the overcast it should be a bit lighter. It only looks this dark in the evening.
