Pure Verbena

#3f37a1
Notes

Pure Verbena (#3F37A1) 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 (245°, 49%, 42%) 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

Pure
adjective

Latin purus, clean, unmixed — applied to color since antiquity for hues that contain only one pigment without dilution by white, black, or another color. Pure red is the textbook ideal: high saturation, mid lightness, no shift. Sits at the bold-bucket center, parallel to true and strong.

Verbena
noun

The cultivated genus Verbena — particularly Verbena × hybrida, the trailing bedding plant in the Verbenaceae family with violet-and-magenta flat-topped cymes used in Mediterranean container gardens. Verbena color refers to a fully bloomed Verbena bonariensis cyme: a saturated, slightly cool deep blue-violet with the velvet finish of dense small four-petaled flowers. Slightly cooler than Vervain and warmer than Liatris.

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.
