Black over any paint will result in black. It's dominant. It can be used to fade from say candy black cherry to black. Maybe used on the front clip. It could be used on the front clip over an entire base of say silver for a candy, then it would give the front clip a darker look. Imagine a 49 Ford Coupe, sprayed in the base color then the nose and tops of the fenders are sprayed black, sparyingly, use a detail gun with the paint pickup screw turned way down. Black paint reduced down is not black candy, I tried it. Try some black with your candy color on a test panel. A little is a lot here. Blue candy with black cherry on the nose/fenders after your black cherry paint. Something a little different there. not just a straight black cherry. Black cherry is awsome, black cherry with downtones, really awsome. This will only be noticed in the bright lights. Certainly a ***** to repaint.
