Direct Pulmonaria

#406ea1
Notes

Direct Pulmonaria (#406EA1) is a true azure 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 (212°, 43%, 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Direct
adjective

From the Latin directus, straight — used as a color modifier since the eighteenth century for hues that read as straightforward and unambiguous. Direct red, direct green: moderate-to-high saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and frank.

Pulmonaria
noun

The genus Pulmonarialungwort, the European shade-garden perennial whose flowers open pink and turn blue as they age (changing pH causes the anthocyanin shift). The color refers to a fresh P. saccharata flower in its blue post-pollination phase: a saturated, slightly cool deep blue with the satin finish of bell-shaped flower.

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.
