Kindled Sphalerite
Kindled Sphalerite (#A39F1C) is a true yellow 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 (58°, 71%, 37%) 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
Old Norse kynda, to set on fire — past-participle of kindle. As a color modifier, kindled implies a saturated-and-newly-lit quality, the bright color of autumn-bonfire-and-stove-fire initial-combustion emission. Sits at the bright-and-warm end of the grid, parallel to ignited and aflame in usage.
A zinc sulfide mineral — both an important zinc ore and a high-dispersion gem with adamantine luster. The yellow variety is mined principally in Spain and Mexico. The color refers to a faceted yellow Spanish sphalerite: a saturated, slightly cool yellow-orange with the gem's signature internal fire (higher dispersion than diamond).
