Using paint that changes color by the temperature outside. I mean changing drastically from red, green, blue, and yellow, not just shade changes as I have seen pictures of online. The new mustang could be called Mustang OZ and advertise it as "A Horse Of A Different Color". I already sent and e-mail to the Michigan Inventors Council and they just sent me a note to do a google search for thermochromic paint cars and I would find several websites, which I did, but everything I found was not my thoughts.
