From my perspective, Penny pulls more bronze than copper, though it definitely is a red-based brown. It’s opaque in 1-2 coats.
I’ve been really into holographics, so when Julep started releasing these last year, I was super excited. Ginger is a scattered holo, and doesn’t have the strong rainbow shift a lot of holos have. Opaque in 2 coats, this one would be great for a more conservative polish wearer who wants to branch out.
