You asked why your mirrors on your black 1994-1996 Toyota Supra and the mirrors or paint on the plastic pieces on my 2000 Yellow Acura Integra Type R does not match the metal surfaces on the car correct?

Short answer: Re-read the question. Different car - different paint.

Long answer:

Due to the picture you provided an answer on my end would be a guess at best. Whereas, different lighting(time of day, reflection refraction, density, intensity, depth of contrast etc.) as well as the camera and monitor you view this on all come into play.

Or it could be simply that I am color blind and I can't tell the difference.

Or it could have been the altitude at Pikes Peak which changed the metaphysical properties of the paint.

Either way, thank you for you interest in my vehicle. I am also a fan of the Supra. Unfortuanately my vehicle is often traveling too fast for anyone to notice this trivial matters.

PS. Next time you see a white Supra look at the rear bumper around sunset or under a gas stations lights at the next street races. At some angles guess what? You already know.
