A couple things converging here. Namely, the exterior painting of my home (a nice rustic red colour), and the Beijing Olympic games. As well, you find that household paints these days have the most luxurious names ever, so I figure why not use pollution as an inspiration (the smog in Beijing seems to be all the rage for instance).
Anyway, here is the colour swath for Beijing, and there’s a few more below.
