Faux verdigris patina effect, achieved with a base of metallic spray paint (a girl's BFF) and 2-3 colors of craft (or acrylic!) paint. For added metallic drama, hit the high spots with some coordinating Rub-N-Buff. (Love that stuff!) Mix it up by layering a bit of olive green with the turquoise. That's my personal fave verdigris recipe - I feel it looks more authentic, has more depth, and is just more interesting looking in general.
