Fortified Hepatica

#1f439a
Notes

Fortified Hepatica (#1F439A) is a true 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 (222°, 66%, 36%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

adjective

Latin fortificāre, to make strong — past-participle of fortify.

Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

Hepatica
noun

The genus Hepaticaliverwort flower, European-and-North-American spring-blooming perennials with saturated deep-blue flowers among the earliest to bloom in temperate forests.
