Indigo

Indigo names a deep blue-violet historically derived from the indigofera plant, one of the oldest natural dyes still in use. The CSS hex is darker than most digital indigos and reads as a near-purple navy. Cultural associations are wide-ranging: textiles, denim, philosophy, music, the seventh color of the spectrum. Editorial, fashion, and contemplative products use it as a primary brand color. Pair with warm cream and brass for heritage palettes, or with deep red for an unexpected accent. Body text against white passes AAA at all standard sizes, making it a confident text color for long-form layouts.
