We have discussed the color issue here before. for decades prior to our current period dealers wanted to sell the cars that were on the ground at their location. Ordering cars and dealer trades were possible but selling from stock was strongly preferred. Thus dealers ordered the most common and inoffensive colors so customers would be willing to settle for white, black, or gray if everything else was to their satisfaction. The lower ranked colors were harder to convince people to accept. I would not take a green, yellow, orange, or purple car under any circumstance.
Which leads me to a question I have always wondered: If there were two cars, each identical in every respect, mechanical, interior, electronic, options, everything the same and one was white and one black would you say those two cars are the same?
If a salesman had one color and another dealer had the other color I believe each salesman would say whichever car was on his lot was the same as the other. What say you?
