This photo is of OPS Light My Sapphire in sunlight when the hidden gold and purple shines in Polish spring to life.
Most of the time, it looks more like this:
Blackened blue with Indigo and shimmer shades very thin. A dark shade of enamel very nice, but not as beautiful as when the sun hits.
This is with three coats; two hands was still a little streaky to take photos of, though happily would wear two hands in everyday life on my short nails.
