Colour schemes in your neighbourhoods?

I do color themes for individual Sims so each of their outfits will usually contain one of two colors. I have occasionally had a group of Sims match a color theme, but this is more likely when there's a specific reason for it, like Dracula's three Brides all wear white, black and red and they match for every occasion. But I've never matched a town population before, that's an interesting idea. Maybe if I ever do my Sim neighborhood version of "The People of Innsmouth" (Simsmouth) I'll do a color palette for it, including the lots.
