This is Square Hue Y2K and Sonia Kashuk Starry Night:
Square Hue was doing Decades sets all of last year (i.e., 2015), so of course when they got to the 90s they had to have Y2K. It's a not-quite black with lots of shimmer. Starry Night is a black (not to be confused with Starry Starry Night, which is not) which has a lot of semi-hidden glitter down in the blackness. It's another one of those subtle glitters.
