The one heart Unicode tells vendors what colour to draw

A relative newcomer, the black heart only entered Unicode in 2016 — decades after the red one — arriving to fill a gap the coloured hearts had left open: a heart for the darker, cooler end of the emotional range. It is a genuine emoji in its own right, not the old monochrome text-heart that appears when a red heart loses its colour, though the two are easy to mix up at a glance.

Its uses cluster around a few moods. It's the heart of dark humour and deadpan — sent alongside a grim joke to signal "I know this is bleak, and I find it funny anyway." It suits goth, emo, and minimalist aesthetics, where a red heart would clash. And it does real work in grief: for some people black feels more honest than red when marking a death or a hard anniversary.

The through-line is tone rather than the absence of feeling. A black heart is not "no love"; it's love or approval delivered dry, styled, or in mourning. Read it the way you'd read someone's all-black outfit — a deliberate choice about mood, not a lack of one.
