Suffocating Indranīla

#193691
Notes

Suffocating Indranīla (#193691) is a deep blue with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (226°, 71%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Suffocating
adjective

Latin suffocāre, to choke — present-participle of suffocate. As a color modifier, suffocating implies a deep-and-overwhelming-and-pressing quality where the hue overwhelms the eye's capacity to discern surface detail. Sits at the deep-and-overwhelming end of the grid, parallel to smothering with breath-restricting register.

Indranīla
noun

The Sanskrit word for sapphire — combining Indra (the king of the gods) and nīla (deep blue). Used in classical Hindu jewelry vocabulary for the deep-blue gems of Indian royal regalia. The color refers to a faceted Kashmir indranīla: a saturated, slightly cool deep blue with the gem's signature internal velvet.
