40+ years ago I worked in a body shop, the paint cabinet/locker had about 50 different gallons of white and 1 gallon of black. I asked the boss what was the deal, he said black is black. They repaired a lot of cars while I was there and the black was a dead ringer on every car. I'm not a fan of the clearcoat over or the new metallic blacks. I think the black at the shop was Dupont Centari. On occasion he would get a pint of mixing black for matching dark browns, I was told it was a very intense black for adjusting tone. The painter was a da vinci. 1 of 3 painters I would trust. Choice was easy way back then enamel or lacquer, black was black.
