Bleak Akāsh

#0a3a9c
Notes

Bleak Akāsh (#0A3A9C) is a deep azure 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 (220°, 88%, 33%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Bleak
adjective

Old Norse bleikr, pale — sharing root with English bleach. As a color modifier, bleak implies a deep-and-cold-and-comfortless quality, the dark gray-pale of Yorkshire-Moors and Hebrides late-winter atmospheric-light. Sits at the deep-and-cool end of the grid, parallel to grim and bitter in atmospheric register.

Akāsh
noun

The Sanskrit and Hindi word for sky or space — used in classical Indian philosophy as one of the five elements (pancha mahābhūta). Akāsh-bhūta names the elemental sky-blue in Vedic cosmology. The color refers to a North Indian summer sky at midday: a saturated, slightly cool deep blue with the optical brightness of subtropical atmospheric scatter.
