China glaze Turned Up Turquoise is a very awesome colour it goes on so matte and is just so cool!!!
But because it acts like a neon when u put it on and it drys it doesn't shine its very flat so you do have to use some sort of top coat or buffer.
Other then that its a great colour
Also theres a lot of colours similar to it like china glaze four leaf clover, l.a colours automatic and Ardene's matte of blue
