I think this is a good idea since almost all car manufactors have "their own colors" and some are even pretty famous like the Rossa corsa

Wikipedia
"Since the 1920s, Italian race cars of Alfa Romeo, Maserati and later Ferrari and Abarth were (and often still are) painted in "race red" (Rosso Corsa).
This was the customary national racing color of Italy, as recommended between the World Wars by the organizations that later would become the FIA.
It refers to the nationality of the competing team, not that of the car manufacturer or driver.
In that scheme, French-entered cars such as Bugatti were blue, German such as Benz and Mercedes white (since 1934 also bare sheet metal silver),
and British green such as the mid-1960s Lotus and BRM, for instance."
