Feria is my favorite dye, so it's definitely going to be one of those. You can see them here at the hard-as-hell-to-navigate website: http://www.lorealparisusa.com/frames.asp#haircolor/index.asp
Sunset Blaze -- This is the one I have right now, though it's faded. It's a little lighter than the others, a little more coppery, a little more natural. I've gotten a lot of compliments on it. The website describes it as "a burst of fiery auburn."
Blowout Burgundy -- This is what I had at DragonCon last year. It's a really, really dark burgundy. Maybe too dark to look right on me. I'm not sure.
Ruby Fusion -- I had something close to this when I was on Jeopardy. It's supposed to be "the very richest of all auburns," but it tends to look dark on my hair.
