History, Usage, Psychology & Design Ideas for #100B16

Obsidian Shard (#100B16) belongs to the Indigo color family.

This deep, saturated shade conveys authority and richness. Deep tones are favored in luxury packaging, evening-event branding, and dark-mode interfaces where they provide dramatic contrast against lighter elements.

Historical Background

Indigo dye—extracted from Indigofera plants—has been used for over 6,000 years, with the oldest known samples found in Peru. It was the foundation of the blue-dye trade across India, West Africa, and the Americas, and its economic importance rivaled that of spices. Levi Strauss chose indigo-dyed denim for the first blue jeans in 1873, cementing indigo's place in everyday fashion worldwide.

Design & Usage Tips

Indigo occupies the territory between blue and purple, lending depth without purple's flamboyance. It is excellent for evening-event branding, high-end fashion, and editorial design. Pair indigo with soft gold or warm white for a sophisticated contrast, or with coral for a contemporary editorial palette.

Sitting on the cool side of the spectrum (hue 267°), it promotes a feeling of calm distance and intellectual clarity, which is why cool hues dominate corporate identities, healthcare design, and productivity tools. At 33% saturation, the color has a muted, sophisticated quality that pairs well with bolder accents. It works as a background, a border, or a secondary element in layered compositions.

Psychological Impact

Indigo conveys depth, wisdom, and introspection. It carries the trustworthiness of blue with a hint of purple's creativity, appealing to brands that want to appear both reliable and imaginative—think higher education, think-tanks, and creative consultancies.

At just 6% lightness, this is an extremely dark shade that approaches black. It is best reserved for text, thin borders, or dramatic full-bleed backgrounds paired with light typography.

Creative Design Ideas

Use indigo as a full-page background with centered white text for impactful statement pages. Combine indigo with copper accents for a rich, modern luxury feel in packaging. In web design, indigo sidebar navigation with white icons creates a polished, app-like interface.
