I decided to go with ourple for New Years Eve, and I wanted it to sparkle. So I grabbed a holographic polish by Teeez!, called Outta Control and one by Nubar, called Violet Sparkle.
I've tried all kins of lighting and settings from my cam, but they all turned out much more blue then it really is. Violet Sparkle really is a bright violet and Outta Control is a lilac/purple.
I applied Outta Control over the whole nail, and then applied some Violet Sparkle on the tips. Not really in a straight line, just a bit messy, to make the colours flow into eachother a bit more.
Daylight without flash:
It's all much more pink/redtoned than above.
