Fresh Heliotrope

#634e92
Notes

Fresh Heliotrope (#634E92) is a true indigo 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 (259°, 30%, 44%) 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

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Heliotrope
noun

The genus Heliotropium — the cherry pie plant, named in Greek for its supposed habit of tracking the sun (heliotropism). The color refers to a fresh garden heliotrope cluster in late summer: a saturated, slightly red-shifted deep purple-blue with the matte finish of densely packed forget-me-not-style flowers. Cooler than mauve, warmer than indigo, with the perfumed weight of a flower whose vanilla-cherry scent fills a greenhouse.

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.
