I think Orly Plastic Jungle would be a good polish for St. Patrick's Day although it is hard to photograph accurately. Fancy Gloss Rust Shards is a good gold looking flakie which I will be wearing over 17th March.
This is another polish from the Aqua Aura collection with shy shimmer, I tried taking photos in various lights and couldn't get the pink shimmer to show up how it does to the eye.
