Grounded Crocus

#4647ab
Notes

Grounded Crocus (#4647AB) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (239°, 42%, 47%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Crocus
noun

The genus Crocus — small autumn or spring corms that flower before their leaves emerge, push through snow in March, and include C. sativus, the source of saffron. The color refers to a fresh blue-violet spring crocus: a saturated, slightly violet-shifted deep blue with the satiny finish of a six-petaled cup catching morning light. Cooler than amethyst, warmer than iris, with the seasonal weight of a flower that arrives weeks before everything else.
