Today I bring you Sally Hansen Insta-Dry Fast Dry Nail Color in Bronze Ablaze.  This is from the Fall 2011 collection for Sally Hansen.  Bronze Ablaze is a little bit of a chameleon, but not necessarily a duochrome.  Depending on the lighting and/or what you're wearing it looks like a warm bronze with green undertones, or a deep olive green with golden shimmer.  You can see this in the pictures below, depending on the lighting.

Without the flash, the bottle looks green. 

Swatch above, picture taken without the flash.  This is the "green" version of the polish. 

Picture above taken with the flash.  This looks more like a deep penny bronze/copper with the slightest hints of golds and greens (in the bottle).

Swatches are two coats.  This covers really well, and drys quickly (hence the name).  I also added a top coat of Seche Vite just to speed up the process. 

Very, very pretty - this definitely reminds me of fall and the changing leaves.  A gorgeous, warm shade that might satisfy your need for Chanel's Peridot, although it's definitely not a dupe...just a similar type of color.
