No, but you would have to stop it first if not for license plates.

Absent any other evidence, does the color of the car not matching the description on the plate registration mean that that either the car or the plate is probably stolen?

A non matching plate would be probable cause to make a stop to check IMO.

If the plate doesn’t match the vehicle description it would be reasonable to assume that it was an improper plate.
