Intuition, depth, cosmic wisdom
Indigo sits between blue and violet in the visible spectrum — Isaac Newton famously insisted on including it as one of the seven rainbow colors despite its narrow bandwidth. It carries the depth of the night sky, the intuitive wisdom of meditation traditions, and a quiet mysticism that sets it apart from both its neighboring colors. Brands use indigo when they want intellectual depth without purple's overt luxury signals.
