For the warm vs cool prompt for the challenge I decided to do a gradient. I really love how this turned out.
The colors I used are: Zoya Sooki, Sally Hansen Crushed, Finger Paints Art Nouv-Yellow, China Glaze Def Defying, China Glaze Electric Beat, and China Glaze Gothic Lolita.
I then stamped over it with KleanColor Metallic Jungle and Metallic Pink using MoYou Sailor 03. I topped it off with NYC in a New York Minute Top Coat. But I wanted to see what it looked like matte.
And this was the final version after two coats of NYC Matte Me Crazy and one coat of Orly Matte Top. Didn't go as matte as I wanted but I still like the softening of the gradient, especially on my ring finger.
