This may be due to the physical principle known as "redshift".
When an object is moving quickly away from you (close to the speed of light) the curves in its wavelength stretch out. Whoah. Watch that radar whiz.
The object looks to you as if it is changing to a color with longer spaces between curves. (The object also gets shorter, but that's another story.)
You could say that the speed of your data transmission is so fast that it causes the color of the car to shift. Another possible explanation is that we made a mistake. But the right answer seems to be that it's just the magic of Old Town.
