Heroic Sapphirine

#2f3a9f
Notes

Heroic Sapphirine (#2F3A9F) 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 (234°, 54%, 40%) 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.

Etymology

Heroic
adjective

Latin hēroicus, of a hero — derived from Greek hērōs. As a color modifier, heroic implies a saturated-and-monumental-and-victorious quality, the deep-rich color of Wagner-and-Sibelius late-Romantic-era musical-and-painterly heroic-mode. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and valiant.

Sapphirine
noun

A magnesium-aluminum silicate gem — distinct from sapphire (corundum) — mined principally in Madagascar, Sri Lanka, and Greenland. Sapphirine is one of the rarest gem materials. The color refers to a faceted Madagascan sapphirine: a saturated, slightly cool deep blue-violet with the gem's signature internal warmth.

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.
