Crushing Larvikite

#0c1148
Notes

Crushing Larvikite (#0C1148) is a deep 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 (235°, 71%, 16%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary yellow. 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.

Larvikite
noun

A monzonite igneous rock — quarried near Larvik in Norway — distinguished by the iridescent blue play-of-color in its feldspar crystals. Used as ornamental building stone and gem material. The color refers to a polished Norwegian larvikite slab: a deep, slightly cool dark blue-gray with the iridescent satin finish of labradorite-style feldspar.
