Punchy Larvikite

#407bdb
Notes

Punchy Larvikite (#407BDB) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (217°, 68%, 55%) 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

Punchy
adjective

A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.

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.
