Sturdy Asmān

#3f79e8
Notes

Sturdy Asmān (#3F79E8) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (219°, 79%, 58%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

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.
