That’s because da red wunz go fasta. Requires extra points to buy, more spensive.

House paint can use slag from mines, making it a rest product and thus very cheap.

Cars use much fancier stuff.

I find that a bit hard to believe, seeing as the paint of a car affects mpg through air resistance, luxury cars often add in glitter, and all of it has to be applied through air brushing

Maybe at one point, but I'd be beyond shocked if red was meaningfully more expensive. There are also the myths that red cars cost more to insure and get pulled over more, like with those myths there might be a tiny kernel of truth, but the statements probably aren't true outside very specific historical conditions

That's because of our evolutionary desire to look for ripe fruit. So, we want red thing.
