Overall I would say that I prefer to use holographic finish polishes, something I like about them is that they are easy to remove unlike glitter polish. Also they can be particularly stunning in direct sunlight.
The First Avenger is a duochrome which meant it was difficult to photograph, I hope between the two photos I have shown it correctly. I also have this polish in a holographic finish which you can see here.
I think from my collection my favourite 'ugly' polish colour would be a mustard yellow. Something I seem to reach for in Autumn rather than Summer but still it isn't a colour you would look at and go "ooh beautiful shade" but I do like it in Autumn.
