On my nails are China Glaze's "Hook and Line" underneath a coat of "Fast Track", both from the Hunger Games collection. Both of these colours are sort of metallicy, but Hook and Line is more of a silvery metal colour, while Fast Track is a bit more champagne/gold. I really love the way layering the two turns out, it's a very unique colour!
By the way, please ignore my messy fingers. I clearly didn't clean up my nails very well before I took this picture, haha. :)
