The latest round of When Colours Collide ended yesterday and here's my entry.
The three given colors I used as a gradient base, Essence Wild White Ways, Catrice So Suit! and Essence Black Is Back. I started with one coat of the white polish and sponged on the gradient with two coats.
My fourth color is MoYou London Mango Tango, a stamping polish I'd call neon coral (is there something like neon coral?). I used a pattern from MoYou London Holy Shapes plate 04, secured the stamping with one coat of Maniology Smudge Free Top Coat and added one coat of Essie Matte About You top coat.
