Submerged Khram

#1c3178
Notes

Submerged Khram (#1C3178) 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 (226°, 62%, 29%) 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

Submerged
adjective

Latin sub-mergere, to plunge under — past-participle of submerge. As a color modifier, submerged implies the cool, deep, slightly-shifted quality of a hue viewed through a layer of water or glass. Sits at the deep-and-cool end of the grid, parallel to drowned and sunken in usage.

Khram
noun

The Thai word for indigo — used in the natural indigo dyeing of Phrae province textiles and the mor hom (indigo work-shirt) of northern Thailand's farming tradition. The color refers to a freshly khram-dyed mor hom: a saturated, slightly cool deep blue with the matte finish of Thai-style indigo cotton.

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.
