Dull Violet Black is a deep aubergine that verges on black, and against it Citron Yellow, a sharp acid olive, flashes like brass. Brown sits in between as warm leather. The feeling is moody and autumnal, like an old apothecary cabinet with its drawers half open. Use it for a whisky label, a dark academia book jacket or a menswear brand, where the yellow reads strongly on the near-black.
