Neat Tiānlán

#05a7a8
Notes

Neat Tiānlán (#05A7A8) is a deep cyan 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 (180°, 94%, 34%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Neat
adjective

Old French net, clean / pure — sharing root with Latin nitidus. As a color modifier, neat implies a clear-and-orderly quality where the hue carries the well-arranged visual register without clutter or excess. Sits at the crisp-and-orderly end of the grid, parallel to trim and tidy in usage.

Tiānlán
noun

Chinese for sky-blue — combining tiān (sky) and lán (blue). Used for the pale blue of clear-sky painting in Chinese landscape tradition and the tiānlán-cí (sky-blue glaze) of Song-dynasty porcelain. The color refers to a Song tiānlán glaze: a soft, slightly cool pale blue with the high gloss of fired ceramic 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.
