I forget what it was, something I read or watched... But there's a link between the colours society picks for clothing, cars, etc. that correlates with society's general mood on things. Monotones are negative or unsettled. When society is happier, it tends to go for colours
Oh you wonder why I always dress in black?
Why you never see bright colors on my back?
And why does my appearance seem to have a somber tone?
Well there's a reason for the things that I have on.
Maybe the changes in color preference, but no way color preferences alone are correlated. Some cultures just prefer more color by default, and I'm pretty certain it isn't because they're happier. They just have a different default. I'm sure that default can change over time too, and this chart is also probably swayed by the fact silver cars tend to resale better, so sometimes people don't choose their preference, but make a logic based decision.
A lot of guitars were painted with DuPont automotive paint back in the 50s, so if you want to know what the popular car colors were you could go check Fender, Gibson, and Gretsch's custom paint jobs from that era.
Obviously it won't give you the kind of data from this chart, but I like to shoehorn that little bit of trivia wherever I can. My buddy has a gorgeous surf green telecaster that is exactly the same color as the Chevy Bel Air (minus the rust spots and poorly maintained interior) he used to drive back in high school 25 years ago.
I owned a body shop between 2003-2009. The graph is somewhat deceptive. The naughties saw a large increase in the number of pearl additives that made their way into base coats. In particular, the emergence of pearl additives that could be mixed directly into a single base color coat became available. Previously pearls existed, but they almost always required a 2 part color coat where the base color was sprayed and then a second layer was sprayed with the dry pearl mixed with a clear binder, then the 2 part urethane clear coat was applied.
Two coat systems like this behave more like an old school candy paint, AKA like a dye on top of a base color. This means any overlap error in the spray pattern amplifies the problem, and usually means the job must start over. With candies it is a much bigger challenge that is more noticeable, but it is still an issue with pearls. I could explain it in detail, but it mostly has to do with the paint "flop" or in other words how the color shifts based on the angle it is viewed from. With 2p pearls, it is entirely possible to paint a panel where the perpendicular view of a freshly painted panel matches perfectly, but the a tangential view does not match at all and is very noticeable even to the untrained eye. There are many other issues as well when it comes to repairing damage to a 2p pearls. The factory does not have many of these problems. However, the main body of the vehicle and many small parts are painted in separate operations. The potential variance in a 2p pearl means the extra parts may not match close enough even from factors as small as an ambient temperature or humidity fluctuation that alters how and where the atomized spray contacts the surface.
After the creation of many 1p pearl paints, a lot of potential color variety became possible in the bases like black white and silver. These colors are the cheapest and easiest to spray and match across batches. Consumers generally liked these varieties more as it adds just enough pop to push them into conservative color choices. These colors generally spray like a typical solid color when mixed correctly. So if I repair a small spot and limit the repair to that area, I can spray the color within a very small area and feather it out so that everything matches. Then I must clear coat the whole panel to do a proper fix, although I have hacky tricks to get around this and clear only a smaller area too.
With a 2p pearl, I would be forced to taper the base solid color all the way up to a flop angle like an adjacent panel or hard corner. Then I would need to shoot the clear binder pearl over the entire panel. Then clear coat the thing and pray that the flop matches close enough to adjacent panels.
Oh and 2p pearls can be super expensive as far as paints mostly because there are so many of them and they must be bought in a minimum quantity. If a small repair is needed, a whole bottle is required and many times that one color pearl on one model car is the only time a painter will ever use that pearl. The job may have been a $300 repair, which was $200 in supplies normally, but that bottle of pearl was $150 and your one job just forced me to carry considerably more overhead costs and a special trip to the paint jobber so your bill is now $600. This mostly went away with the 1p pearls that fit into the regular paint system like any other mixing colors. When you see super vibrant colors, with only a few exceptions, like Toyota "Raceway blue", the vibrance is due to a 2p pearl.

I scraped over 3.5m car offers (used and brand new) from polish websites for the past three years. I used python for data aggregation, processing, cleanising and visualization (plt).
When I was young, a friend had a 79 Mustang that was factory ordered by the original owner in Construction Orange, to match some local high school football team color, and it was absolutely beautiful.
I loved the color of my parents green station wagon when I was a kid, and it’s still my favorite color but I don’t think I’ve ever gotten a car where it was a choice
Hypothesis: we're going to see white continue to increase in response to rising temperatures and people getting tired of burning themselves on their cars.
As a car enthusiast, I would accept all new cars being white to combat global warming. I wouldn't like it, but the payoff could be quick and impactful if done at scale and over time. At least white roofs/hoods/trunks. And if moonroof then white interior.
Same with roofing/siding on buildings houses where possible.
Don't mistake customers being forced to take what manufacturers offer for popularity.
Anecdote time: I was prepared to buy a brand new Tacoma shortly before the pandemic, but didn't because Toyota couldn't find one for me with the options and color I wanted (a blue TRD Off-Road with a manual transmission) anywhere in the entire multi-state region. I ended up buying a used car instead. Most people are not as stubborn as me, and would have settled for whatever shitty color was actually available.
I have no memory of green cars being popular in the 90's although it seems like they would have stood out (and been pretty ugly, probably). Weird how memory works.
I find it interesting that red seemed to be such an unpopular color throughout the 21st century. I used to drive a 2015 Toyota Corolla in "Barcelona red", and this exact body and color seemed to be very popular in the area. I hardly can go a few hours on the road without seeing two or three copies of my old car. I also find it humorous how unpopular yellow has been historically. I would love a yellow car.
In fact, there is a local construction/home remodel company whose "brand color" is this sort of dead-grass yellow color, something like hex #F6F0C0, and they custom-paint all of their company cars to be that shade, and they stand out pretty clearly against the wasteland of plain-colored, boring cars on the road.
