Essie Steel-ing the Scene is very close to Chanel Kaleidoscope. It's Chanel without the shimmer.
Sephora By OPI "Charge It" is kind of close to gold fiction. The finish is pretty much the same, but Chanel is more shimmery and I believe closer to being a true gold.
I'm not sure about how these would work with your skin tones, but other gold options (not necessarily a good substitute to Gold Fiction) are OPI Curry Up Don't Be Late (I CANNOT pull this gold off...), Symphony in Gold and OPI I Get a Kick Out of Gold. I don't think there is a good real dupe of Gold Fiction found/produced, yet.
someone painted there toes in a gold on the other thread.. that was real close.. but i cant remember the name.. i am going to have to go look and post it.. and i think it was a brand they sell everywhere.
