Refreshing Andalusite

#a1801f
Notes

Refreshing Andalusite (#A1801F) is a true amber 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 (45°, 68%, 38%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Refreshing
adjective

Old French refreschir, to make fresh again — present-participle of refresh. As a color modifier, refreshing implies a clear-and-cool-and-revitalizing quality, the crisp color of Cornish-coast and Hebridean-island fresh-sea-air-and-cool-water revitalization. Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing in usage.

Andalusite
noun

An aluminum silicate gem — pleochroic from yellow-brown to gold-green to red-brown depending on viewing angle. Mined principally in Brazil and Sri Lanka. The color refers to a faceted Brazilian andalusite seen along its strong axis: a soft, slightly muted warm gold-brown with the optical complexity of pleochroic stone.

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.
