Color matching is a different story.

Matching any kind of pearl paint is a BITCH if you are only do a partial repaint(i.e. just a bumper cover or whatever) Case in point may dad painted my cousin's Neon this burnt orange pearl color. Its something like the color on the newer Sunfires etc. He had some areas that had to be redone on the passenger fender and door. He taped everything back off and redid them. In the sunlight the shade of the color is very different.
One thing to add in the 19 years of my dad painting cars he has done a total of 2 black cars. And probably has close to 100 paint jobs under his belt if not more. He talked me out of painting my car black, then when my brother was talking about doing his Neon in black my dad told him he wouldnt touch the car if my brother was going with black.
