Inside the 23-Dimensional World of Your Car's Paint Job

We're continuing this week with a little more on the art theme. It's a very different kind of art from last week's memory metal flower, but there are still pedals involved. (groan)

Wired magazine has a brilliant article detailing the incredible process of color matching the paint on a repaired part of a car to the paint on the rest of the car. At first blush, the process seems awfully simple - pick up a can of the paint used to paint the car originally. Things are a little more complicated than that, however, as no repair shop is going to stock 50,000-60,000 different paints (the number of car colors on the road according to the article), no car in need of repair looks exactly like it did when it first rolled off the production line. and because the original paint job on most cars involves twenty three different dimensions to the color - sparkles, coarseness, red, blue, green, angle, diffuse coarseness, and so on.

The knowledge and skills involved in color matching are absolutely mind-boggling. There's an art to it all.
