For Light As Air, I used a base coat of Seche Natural, 2 coats of polish and a top coat of Seche Vite. For Marley, I used a base of Zoya Anchor, 2 coats of polish and a top of Zoya Armor.
In the sun, you can tell just slightly that Marley is darker than Light As Air but it's not completely obvious.
However, in the shade, it's a little bit more obvious when looking at the ring and pinkie fingers. I'm kinda torn - I'm not sure which one that I like better... that's why I'm all about having both! ^_^
