Infused Diǎnlán

#172584
Notes

Infused Diǎnlán (#172584) is a deep blue 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 (232°, 70%, 30%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Infused
adjective

Latin infundere, to pour into — past-participle of infuse. As a color modifier, infused implies a deep-pigment-and-warmth where the hue has been filled from within with the source dye. Sits at the deep-and-saturated end of the grid, parallel to suffused and steeped in usage.

Diǎnlán
noun

Chinese diǎnlán (深蓝) — deep blue, used for the saturated blue of Ming-dynasty cobalt-on-porcelain underglaze and the deep-blue silks of Han-period imperial robes. The color refers to a Ming-dynasty diǎnlán cobalt-on-porcelain plate: a saturated, slightly cool deep blue with the high gloss of fired porcelain glaze.
