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.
I don't tend to wear a lot of neutral polishes, nearest to that would be OPI Alpine Snow with some sort of opalescent topper and then black stamping over the top. Alpine Snow is something I surprisingly reach for quite often.
