Hello everybody!
It's a nice blue colour with lighter blue/greenish duochrome-like effect. Yes, I suck at explaining colours! In the pictures it looks mostly blue though, but in some lighting it's visable.
Blue's Brother applied very nicely. I only bothered to do a clean up on my ringfinger, the other fingers are "freehand", so it does apply very easily and evenly!
Thanks for reading :)
