Welcome to a brand new year - new color technology!
BMW unveiled a color-changing car which uses E-ink, similar to how the Kindle reader screen works. This does not emit light, but reflects light and allows items like ebooks (and this car's color) to be visible in broad daylight. The demo car is limited to a black and white palette, but they claim that the technology can be expanded to include colors. The idea is that you can change the color of your car according to your mood.
I wonder if you can program it to be "black" to absorb heat when it's cold outside - and white in the summer?
