What Is Indigo? The Mystical Bridge Between Blue and Violet
Indigo is a deep, rich color that exists on the boundary between blue and violet in the visible spectrum. Sir Isaac Newton famously included indigo as one of the seven colors of the rainbow, positioning it between blue and violet. Named after the indigo dye (Indigofera tinctoria), one of the oldest dyes in human history, indigo carries centuries of cultural and spiritual significance.
The standard indigo hex code is #4B0082, a deep blue-violet that evokes mystery, intuition, and profound depth.
