Black balloons bring a sharp, grown-up finish to a party, whether you're marking a big-number birthday, an over-the-hill theme or a black-and-gold colour scheme. Shop them in latex packs and foil shapes, including black number balloons. Mix them with other plain colour balloons from the wider balloons range, or send a ready-made black balloon in a box. Black works best with one bright accent or a metallic, so pair it with gold or silver rather than another dark shade, and tie it in with the rest of your black party supplies.
