This is Insta-Dri Chop Chop Copper, which was in my Sally Hansen favorites:
This was an LE polish so it's probably not widely available, but I really like it a lot. As you can see it's a pale metallic copper. I mostly don't wear it on its own (which takes 3 coats) - instead I wear it as a layering polish. On top of something like that brown below it on the wheel, it's stunning.
