These are the final two of my four Tronica polishes. Electra Magenta is a gorgeous pink with a great formula. It was easily opaque in two coats. This one is definitely my favorite in the whole collection. Hologram is a simple silver holo, nothing super special, but I think it looks great with the other Tronica polishes. Overall I like the formula of the Tronica collection. Anything that requires two coats or less makes me happy.
(The turquoise polish is China Glaze Techno Teal)
