The Blue Heart emoji shows a solid blue heart. It usually represents trust, loyalty, calm affection, or support without the strong romantic signal of a red heart.
People use it for close friends, family, teams, causes, and anything associated with blue. It can read as gently affectionate or deliberately platonic, though context still matters. Some fandoms and brands also claim it as a signature color.
