This mani features an old, hard-to-find black label OPI called Glacier Bay Blues, which has a navy blue base with purple-to-green duochrome shift. The ring finger accent is BB Couture Pipe Bender, which has a muted dark green base with some subtle purple duochrome shimmer. I used three thin coats for each (although the BB Couture could easily be a two coater) plus top coat.
This first one is a phone pic in sunlight, where the duochrome effect is less apparent:

I added some stamping to the accent nail that didn’t really turn out, since it’s not very visible, but here it is anyway. I used my bottle of Kleancolor Metallic Sapphire, which is strangely no longer its original royal blue colour, but is now a dusty dark purple. I’ve seen fading blue pigments before, but this was kind of strange in that it turned really quite purple! It almost looks like OPI Ink Suede now, except more muted and even more purple. Anyway, it wasn’t enough of a contrast to Pipe Bender to show up well, unfortunately, and I liked the mani better without the stamping. The image is from plate Hehe-024.
