1965 Dodge Dart Charger

Yes. Color changes over the years.

The sunlight and the oxygen in the air are the mayor factors. Depending on which color the car is painted with, the change occurs more or less clear to the eye. For instance, a red paint fades more over a ten year period (if not clear coated) than a white paint.

The color also changes depending if you look at it direct sunlight or in the dark.

Even if you find a painted surface of the car that has never been exposed to direct sunlight it differs from the day it was painted. Not much but a little.

Additional impact of color is humidity, pollutants and how the car has been stored. Indoors makes the color fade less than stored outdoors. Direct sunlight will bleach the color faster than total darkness.
