Frank Virgo Lazuli

#125f9b
Notes

Frank Virgo Lazuli (#125F9B) 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 (206°, 79%, 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

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

Virgo
modifier

Latin virgo, virgin-or-maiden-of-the-zodiac. As a color modifier, virgo implies a maiden-and-earth-sign-and-Mercury-ruled-mutable-earth quality, the visual register of Hellenic-Virgo-and-Astraea-maiden hand-maiden-and-earth-sign-and-Mercury-ruled-mutable-earth Hellenic-Virgo-and-Astraea-maiden-and-Spica-grain virgo-and-maiden-and-earth-sign surfaces under Hellenic-Virgo-and-Astraea-maiden-and-Spica-grain late-summer-and-August-and-September mutable-earth-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to leo and libra in usage.

Lazuli
noun

Passerina amoena, the lazuli bunting — a North American songbird whose males display saturated deep-blue plumage with white wing bars and chestnut breasts. Named for the gemstone (lapis lazuli) the bird's plumage resembles. The color refers to a male lazuli bunting in breeding plumage: a saturated, slightly cool deep blue.
