This is China Glaze This Is Tree-mendous:
All Wrapped Up, the blue-violet, and Put A Bow On It, the blackened pink. This has a pretty similar formula to the other two, except that it seems to have a clear base, which makes it paler-colored. However, my swatch here is only one coat, so that made it even lighter. Later I put a second coat on and it did darken up to more like the bottle color.
(I had originally swatched this last summer, and I was apparently feeling more verbose that day so that entry goes on about how it looks with top-coat and so forth, if you're interested!)
