Twilit Larvikite
Twilit Larvikite (#283A89) 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 (229°, 55%, 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
An adjectival form of twilight, coined in the late nineteenth century. Twilit describes a color seen at twilight — the slight cooling and desaturation that low ambient light introduces. Sits in the deep-and-cool corner, lighter than somber and bluer than shadowed. Almost exclusively literary.
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.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
