I thought The Donmar would be a dupe for the typical flake polish like Nubar 2010 and GOSH Rainbow. It's not. It's less intense on the red/gold scale and has a strong green flash. I read a post about this polish that described it as being holographic and it's not. It's a duochrome flake polish.
It's subtle without being a wallflower. I wore The Donmar over Misa Moody Model which is a clay brown creme. Some tipwear but we are all friends here and that means you will ignore it.
