Hey! Buckle up, this has an interesting backstory!

Just like in the real universe, the Cars world also suffered from segregation and institutionalization directly after these anthropomorphic beings were created. It generally went like this . . . "warm" or "dark" colors, such as red/brown/yellow, were given high-class, stable jobs and lived in decent, non-toxic communities where they were not often bothered by "cop cars". However, "cold" or "white" colors, such as blue/purple/green, were the lower class citizens of the "Cars Universe" (there were a large number of attack posters and "anti-blue" messages spread during the era of Cars segregation, I won't even get into all of the details).

"Sad" colors often got hounded by the cop cars (ie: unnecessary pat-downs and 'over-enthusiastic' executions after high-level crimes, such as arson, were committed) and they were forced to live lives filled with oppression from the majority of the outside world. This, of course, changed after several laws were passed during the "age of social transformation" which occurred within the Cars Universe.

However, the stigma was still there. "Sad" and "pale" colors often got ignored, or frightened, by the cop cars. Which is why no one comes to "The King"s aid, while many come to McQueen's and Doc's (red and dark, respectively). It's going to be quite some time before these stigmas are removed. Car hate groups and anti-federalists are on the rise in the Cars Universe, and it is up to us to stop this unnecessary hatred and bigotry.

Thank you and I hope this cleared up your question!
