Crushing Sapphirine

#1a3696
Notes

Crushing Sapphirine (#1A3696) is a true blue 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 (226°, 70%, 35%) 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

Crushing
adjective

Old French croissir, to crash / break — present-participle of crush. As a color modifier, crushing implies a deep-and-overwhelming-and-weighty quality where the hue exerts maximum visual force. Sits at the deep-and-weighty end of the grid, parallel to pressing with destructive register.

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.
