Dark Como

#1f2d88
Notes

Dark Como (#1F2D88) 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°, 63%, 33%) 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

Dark
adjective

Old English deorc, dark, gloomy — cognate with the German dunkel and the Latin terra, earth, both pointing to a base meaning of covered or obscured. As a color modifier, dark sits on the lightness axis only: it says nothing about hue or saturation, only that the value is low. Used across every adjective bucket the engine routes to when L < 0.40.

Como
noun

Lake Como — Lago di Como — in Lombardy, Italy. The deepest lake in Italy at 410 meters. Como color refers to mid-depth Lake Como water seen from Bellagio: a saturated, slightly cool deep blue with the optical depth of Alpine glacier-melt water.

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.
