Some blacks have other colors added like white or yellow so they match the poorer quality OEM black used. I would just use the blackest toner ( straight out of the can ) in the system used by the shop that paints your car. Like was said before the strongest paint you could use is single stage black because it is a stand alone coating with hardener in it and then clearcoat that for UV protection and so when you buff the paint job you arent taking off the color. Single stage with clear over it is very chip resistant.The main reason for basecoat in thr first place is metallics and pearl colors not solid colors.
