Car Paint Changes With Temperature

PlayfullyClever writes "It's now common to build materials which can change colors depending on their surrounding environment because of progresses made in colloid chemistry. But now, German researchers have gone a step further. They've used ion bombardment and gold metallisation to produce new particles whose bonding behavior can be chemically tailored. This could lead to new shimmering car finishes which can change with temperature or humidity, new cosmetics, but more importantly, to new applications in optical data processing"

I just lay in bed in my hypercolour shirt, and when it started to change colour (due to the fever beginning to rise), Mum could tell the meds had worn off and I needed another dose. Better than mucking around with thermometers every half hour or so.

    This could be used to change the car to a color that attracts heat when it's cold, and repels heat when it's hot. It might help somewhat with the heat and cold, but would the particles add more heat so the heat repelling functions don't really work?

      This would actually be a practical use of this paint. In racing, when a team needs to quickly diagnose an engine problem clearly as a result of a bad cylinder (bad spark plug), they will put chalk streaks on the headers and see which one melts the slowest, thus pointing to the problem. If they could create a powder coat with the same properties and paint even a small part of the headers, one could visually inspect for misfiring cylinders and, if controlled well enough, could quantify cylinder-to-cylinder variations visually.
