But they sure are gorgeous, yes? Base is Rimmel "Steel Grey" and the marbling colors are Sinful Colors "Tokyo Doll", Zoya "Ki", and China Glaze "Seduce Me". I marbled two on one hand, three on the other. A pretty fun mani, IMO!
On a side note, the Rimmel's name confuses me, as it's more of a taupey fig color than grey. What's with that?
