Salon Perfect Ivy League

I love, love, love this color of polish.  I actually have a few of these shades and I can honestly say that I think they are all dupes.  I'll have to show you sometime.

Ivy League is a dark shimmering green that is almost black in the right light.  It's one of those polishes that glows from within.  I really love how it looks on my nubs too which is something I wasn't expecting.  So what do you all think of this color?  Isn't it perfect for for the Christmas season?
