BMW now offering a car that changes colors with touch of a button

[Carolina Jim]

The color-change effect comes from E Ink, the same electrophoretic technology used for e-readers. The ink is comprised of millions of microcapsules about the diameter of a human hair, suspended in an exterior wrap.
The ink contains negatively charged white pigments and positively charged black pigments. An electric current can change how much of each pigment collects at the surface of the microcapsules, allowing the color to change between white, black, and gray with the push of a button. However, that also means the options are limited to those three colors.

Perfect car for criminals.

wait, can a scratch in the paint interrupt the electric current making that area unchangeable? If so, I see a future of 2 tone spotted cars
