I entered these into a contest where I had to recreate one of @nailartdiary's manis, and I absolutely loved this one (go figure, it is rainbows)!
Polishes used:
Base: OPI Push & Shove
Red: OPI Red my Fortune Cookie
Pink: OPI That's Hot! Pink
Orange: Avon Voltage
Dark Yellow: Sinful Colors Pull Over
Yellow: Zoya Pippa
Green: Wet'n'Wild Split Pea Soup
Blue: OPI No Room for the Blues
I just love how these turned out. They're so much fun, and you can never go wrong with rainbows and gradients! ^.^
