Gradient is done with fan brush, with Essie Watercolor sheer polishes, and I don't think I ever done gradient this way. I kind of like uneven, watercolor feel of it.
Base is Essie - White Page, that came in package with both of my mini sets of those polishes. Each came with three different sheer polish and white base.
Sheer polishes used for this manicure are: Muse, Myself (Yellow), Point of Blue (blue) and No shrinking Violet (purple), and I also used Soap Bubbles - Neon Rosa (pink).
Image is from Helen 03 stamping plate, and I stamped it over two nails using Mundo de Unas - Black. After I stamped image, I wanted to paint my palm tree branches with green, and I used Kaleidoscope - Aquarelle tint #3, but this one is not visible at all.
Bright blue I paired my watercolor stormy sea with, is from MoYou London - Baby blue - shown here are two coats, no white base. I got few of MoYou London polishes on great sale few months ago, and I am more than happy with them.
Everything was Topped with love from Love, Angeline.
