I came across
Polished Components last night, after seeing her holo listings while perusing Etsy. She has an Elements collection that she just came out with, with Night and Day components for each element. The Day versions are linear holos, while the Night versions are duochromes with scattered holographic glitter (to represent the stars that come out at night). They're top coats and only sold in minis.
Here's her more detailed explanation.
I think it's pretty cool that her Day versions aren't just clear top coats that happen to be holo. If you look at her swatches, all of them are layered over black, but it doesn't seem that way at all.
I ordered a set of the Day versions, so I'm quite excited to get it and try them out.
