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 don't get it

Maybe it's just me, but what's so great about using this as car paint? Certainly the article could have expanded on other uses. On the other hand, it might pretty good for my low-rider

Possible flaw

[MirrororriM]

I forsee one possible flaw with this technology. I am from Michigan and we see hot summers and cold winters. In winter, your hood will be much warmer than the rest of your vehicle due to the engine heat. I would think you would end up with blotches all over your car. In summer, the air conditioning, I would think, would produce similar results.
