Submerged Bellflower

#422594
Notes

Submerged Bellflower (#422594) is a true indigo 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 (256°, 60%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary lime. 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.

Bellflower
noun

The genus Campanula — Latin for little bell — small to mid-sized perennials whose bell-shaped blue or violet flowers fill rock gardens and herbaceous borders across temperate climates. The color refers to a fresh Campanula medium canterbury bell: a saturated, slightly violet-shifted blue with the matte finish of a single bell-form flower. Cooler than periwinkle, warmer than larkspur, with the cottage-garden weight of a plant that names an entire genus and color.

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.
