I do like this much better than Steel or Strong. It's an interesting color and doesn't look black in low light. It applied nicely, needing only two coats (these swatches are, as usual, over base coat but without top coat). I'm not loving the brushstrokes, though; for $25 I think they should settle out better than they did. I will just have to save this one for when I have steady hands, I suppose.
I couldn't think of a dupe for this in my stash but that did not stop me from doing a comparison. Before Black Pearl was released, a couple people speculated that it might be similar to Borghese Stellare Notte, which has some green in it (visible from certain angles), so I pulled that, plus Maybelline Blackened Teal, an oldie but goodie I got from the Dollar Tree some time back.
Stellare Notte's is too dark and has too much purple in it to pass for Black Pearl. Blackened Teal, though, is a lot closer than I expected. It's darker than Black Pearl but the base color and finish appear to be very similar. I bet it would make a good base for a Black Pearl franken; too bad it's not widely available anymore (thought there are a few up for swap on MUA and for sale on eBay).
I think I'll be keeping Black Pearl.
