Fiery Asmān

#2b91f6
Notes

Fiery Asmān (#2B91F6) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (210°, 92%, 57%) places it in the highly saturated band at a mid 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fiery
adjective

Old English fȳr, fire — adjectival suffix -y. As a color modifier, fiery implies a saturated-and-bright-flaming quality, the bright color of autumn-foliage fall-color and forge-furnace hot-iron emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.

Asmān
noun

The Persian word for sky or heaven — used in Persian poetry for the saturated blue of Iranian summer sky and the asmānī glaze of Persian tile. The color refers to asmānī-glazed Persian tile: a saturated, slightly cool deep blue with the high gloss of fired ceramic. The Iranian cousin of sky.
