With most of those cars, the color wasn't right for the car.
The '53 Chevy; the color was OK, but it was just another Chevy convertible.
The Triumph was the expected dark green color, but it was just another British car.
Chargers aren't supposed to be green, although a kid in my town had a green Hemi Charger, so what do I know.
Pea green on that truck is a poor choice, should be blue/white, red/white or black.
The open Ford should be grey, black, or ideally, Tucson Tan.
Who ever heard of a green Mercedes.
Wrong shade of mustard green on the Olds, looks pukey.
Lime metallic on a Jag? Seriously?
Right colors on the Cad, but it just doesn't pop. Maybe reverse the colors.
The '64 Chevy should be white and a 409.
A GREEN Cobra, really?
I don't mind the green over tan Vette, but I'm a slender market.
The purist in me demands a blue Packard.
The Duster; well I guess there's a butt for every seat. Not mine though.
In sum, green can work well, but only on a very few cars.
