This was a really difficult challenge and I’ve painted my nails four times in a row to get a mani I was happy with. 
This colour polish really changed the way I look at and buy polish. It was one of my first OPIs too.  It’s not the original MPJ which has a denser and coarser holo, but it is beautiful. It doesn’t need much, so I just added a subtle gold highlight.

I know that a deep charcoal brown seems like a weird choice for a colour challenge but this was the polish that makes me look at others more closely to find the unusual finish or shade. If there’s some bright sunshine tomorrow I’ll get another photo to really show the holo off. 
Tomorrow: inspired by a song.
