My shop has a camera that takes three pictures of the paint and adjust the color match on the paint computer. It's spies Hecker paint. Not always a perfect match but gets you in the ball park. Most of the other body shops in my area have a similar device.
My only problem with going that route is.....then they send you to a auto paint supplier, where the minimum is a gallon at around $250.
And, then I have to use my airbrush.
