Normally, when you want to change the paint color on your car, you're facing lots of disassembly, extensive prep work, and expensive time in a spray booth followed by seemingly endless hand blocking. Instead of the conventional method, a new technology might be on the way to make a color change as easy as twisting a knob. It's actually quite similar to the magic General Motors has wrought with their magnetorheological dampers. The variable-color paint works this way: prior to paint, the body gets a special polymer coating that's got paramagnetic iron oxide particles in it. When a current passes through this coating, the ferrous particles change their alignment, which alters the way they reflect light, effectively changing the car's color. The default color when the car's not running is white, which hints at a future of exceptionally bland parking lots if this technology takes off.

      Guys, Pistonheads stole this story from MotorAuthority. It came out yesterday.

      I had talked with an engineering student a couple years ago about research on this method and it was still years and dollars away.
      I keep thinking how great it would be for pool bottoms. Light color and cool in the summer, dark color and absorbing heat in the spring!

        Except that you have to be applying a current to the oxide to hold the color.

        Hey kids jump in the water, its *shockingly* warm...

      Ok who is the main company who is going to wholesale the product.. well rather the oxide coating paint

      Oh no. Now people are going to be changing the colour of the car in time with the music or worse. Great :(

      There's been crap like this out before - it's hardly new.

      I'll stick with various interpretations of "invisible graphite"

      Should be great for law enforcement- imagine that silver impala just turned black and white. The unmarked cars are not easy to spot as it is, imagine it with this!

      Car shopping for the typical female just got alot easier.

      great, get ready for some seriously gross car colors. i can only imagine what the tuner-boys in my neighborhood will come up with for their hondas.

      What if you do a body kit? or get a scrape?

      What if onstar makes the bank robbers car start flashing for easier visibility?

      It would be ridiculous to think safety measures won't be taken with this. I can already see this only working in park.

      And I'd be happy for my heat soaking black car to turn white when I'm not in it.

      cool write-up, i always thought that someone would eventually come up with this technology...
      however, I feel like I should point out (for those who aren't aware) that the car in the picture isn't painted with any special paint, it's actually a special edition volkswagen called The Harlequin... they came factory painted in all different colors.
