Why did Mopar make so many green cars?

Wasn't there something about the police back in the day pulling over the "fast" colored cars? the Plum Crazy, the Go Mango, the Citron yella, they would be police targets. A subtle colored performance car just may creep on by if it just cruised by quietly...true story, when I bought my '70 340 Swinger, it had been repainted silver, by the time I bought it, it looked like gray primer :) story was that the cops were always looking for the car, prolly the only Plum Crazy car in town in the late 70's early 80's...
