Aristocratic Pulmonaria

#0a4da1
Notes

Aristocratic Pulmonaria (#0A4DA1) is a deep azure 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 (213°, 88%, 34%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Aristocratic
adjective

Greek aristokratía, rule by the best — adjectival suffix -ic. As a color modifier, aristocratic implies a saturated-and-noble-and-hereditary quality, the deep-rich color of pre-modern European aristocracy hereditary-class livery-and-armorial-bearings. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and lordly.

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.
