"Fortissimo" is a dark brown, bordering on black with a slightly green undertone. I think people who aren't into polish (= muggles) could easily mistake it as black, but when you take a closer look it becomes obvious that it's not really black, but clearly brown.
The formula is pretty much perfect. Two coats is all you need. There's not much more to say about this polish. It's dark & edgy, but not totally unique. As I wanted the whole collection, I'm happy I have it in my stash, though.
Now to something totally unrelated that I would like to share with you nevertheless. There are still sunflowers blooming in our garden & the tons of rain did them well *yay*
I took the pic below this afternoon:
Thanks for looking :-)
