FWIW here in SF you're on the money: everyone used to dress in motley and calico but these days it's all greys and blacks. I was at the farmer's market behind Stonestown the other day and everyone was in grey and black.
The cars too. My mom has this habit of calling out the colors of cars and she's been pointing it out for a few years now. Cars used to be colorful and now they're drab.
