Two things from designer Mathis Brosseau’s lovely, inky site: 1. Black is likely the most useful “color” in design — as in, it is a definer, a salt, a field and among many other functions, a base. 2. Blacks invoke a gorgeous spectrum of mostly serious modes — the trickster blacks of fonts/texts, the swirling solipsistic reddish blacks only found behind eyelids, the dead flat blacks of clock numerals, the jaunty blacks of cartoon outlines, the salt and pepper blacks of night-watch monitors, the glossy nail polish blacks of coffin lids, the vampire cape blacks of early morning tree lines, as well, the propositional black of death.
