Entombed Picotee

#183484
Notes

Entombed Picotee (#183484) is a deep azure 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 (224°, 69%, 31%) 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

Entombed
adjective

Old French en-tombe, into-the-tomb — past-participle of entomb. As a color modifier, entombed implies the deep, sealed, untouched-by-light darkness of a sepulchre interior of medieval-and-Renaissance European cathedral architecture. Sits at the deep-and-funereal end of the grid, parallel to sepulchral and crypted in usage.

Picotee
noun

A botanical term for a flower with edges colored differently from the body — Picotee roses, Picotee sweet peas, Picotee dahlias all have a crisp white or contrasting band along the petal margin. The color Picotee blue refers to a saturated body-color blue used as the dominant petal field: a saturated, slightly violet-shifted deep blue with the matte finish of high-density flower petal. Cooler than royal, warmer than indigo.

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.
