Urban

New York's a town of neutral tones: the buildings, white, gray, brown, tan. 

 People's clothing tends to be neutral too

so the bling-bling colors of graffiti (suitably placed) are rather fun.

(Here outside a club on 22nd St)

I like the layer upon layer, ripped paper, revealing stuff underneath.

 I enjoy the sort of free-for-all-ness of it.

What bubble-gum colors!

An ephemeral art.
