Dense Asmān

#00459a
Notes

Dense Asmān (#00459A) 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 (213°, 100%, 30%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Dense
adjective

Latin dēnsus, thick / crowded — sharing root with English condense. As a color modifier, dense implies a saturated-and-tightly-packed quality where the hue carries maximum pigmentation per visual unit-of-area. Sits at the bold-and-saturated end of the grid, parallel to thick and concentrated 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
