Indigo’s history begins in ancient India, where it was first extracted from the Indigofera tinctoria plant and treasured as much as gold. This deep blue-violet hue has long carried spiritual meaning across cultures, often linked to intuition, wisdom, and the third-eye chakra in Eastern traditions. Modern psychology recognizes indigo’s power to inspire contemplation and enhance focus, while its mysterious quality bridges the gap between earthly blue and cosmic violet—symbolizing the union of physical and spiritual awareness. Artists and designers value indigo for creating visual depth and evoking inner truth.
Technically, indigo is defined as a secondary color positioned between 275 and 285 degrees on the color wheel. Digital designers use its hexadecimal code, #4B0082, and RGB values of R:75, G:0, B:130, to achieve its deep blue-violet look. In print, CMYK values of C:93%, M:100%, Y:0%, K:17% replicate its rich tone. Indigo maintains strong saturation across media—from digital displays to textile dyes—and its wavelength of roughly 420 to 450 nanometers places it in the high-energy segment of the visible spectrum, ideal for balanced, impactful visuals.
