Studio Black is a near-black at #1B1B1B, effectively neutral. Dark colours show every ridge in the nail plate, so a ridge-filling base coat does more for the finish than the colour ever will.
A crème finish: flat, opaque and even, with no shimmer to hide behind. It is the most forgiving finish to apply and the least forgiving of bad prep.
It paints 18 designs in the catalogue, most often alongside True Black, Snow White and Marigold.
