Ashen Zǐlán

#b3b5d8
Notes

Ashen Zǐlán (#B3B5D8) is a soft blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (237°, 32%, 77%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ashen
adjective

Old English æsce, ash — adjectival suffix -en. As a color modifier, ashen implies a pale-and-grayed-and-drained quality, the pale color of Provençal-domestic-hearth fully-burnt-and-cooled wood-ash residue surface. Sits at the pale-and-drained end of the grid, parallel to wan and pallid in usage.

Zǐlán
noun

Chinese 紫蓝, purple-blue — the deep indigo-violet of late-imperial Qing court silks dyed with cultivated Polygonum tinctorium. Zǐlán color refers to a Qing-period imperial silk court robe: a saturated, slightly cool deep blue-violet with the silk luster of multi-bath fermentation indigo on tussah silk. Distinct in Chinese color terminology from (purple) and lán (blue).
