Submersed Indore

#1b1558
Notes

Submersed Indore (#1B1558) 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 (245°, 61%, 21%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Submersed
adjective

Latin sub-mersus, plunged-under — past-participle of submerse. As a color modifier, submersed implies the deep-saturated-and-cool-shifted quality of a hue viewed through a layer of water, like an underwater coral-reef object seen from a glass-bottomed boat. Sits at the deep-and-cool end of the grid, parallel to submerged with slightly-archaic register.

Indore
noun

Indian princely-state capital (now Madhya Pradesh's largest city) — once an important node on the colonial-era indigo trade routes, with the Holkar royal silks dyed in Bengal-sourced Indigofera tinctoria. Indore color refers to an Indore-made Holkar-court kanjivaram silk: a saturated, slightly cool deep blue-violet with the silk luster of multi-bath natural indigo on heavy zari brocade.
