I used Candeo Colors Mallard over China Glaze Cherish (green) and China Glaze Harmony (purple).
|CG Cherish, CC Mallard, CG Harmony|
Thumb - 2 coats CG Cherish, 1 coat CC Mallard
Index - 1 coat CG Harmony, 1 coat CC Mallard
Middle - 2 coats CG Cherish sponged with CG Harmony, 1 coat CC Mallard
Ring - 2 coats CC Mallard
Pinky - 2 coats CG Charish, 2 coats CC Mallard
I think it looks best on thumb and index so either over the green or the purple.
