Fresh Diǎnlán

#37428d
Notes

Fresh Diǎnlán (#37428D) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (232°, 44%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new 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.

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.
