Sparking Amarillo
Sparking Amarillo (#A1C752) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (79°, 51%, 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English spearca, spark — present-participle of spark. As a color modifier, sparking implies a saturated-and-electrical-emission quality, the bright color of welding-arc-and-Tesla-coil high-voltage spark-discharge emission. Sits at the bright-and-electric end of the grid, parallel to flashing and coruscating in usage.
The Spanish word for yellow — and the Texas city named for the surrounding subsoil clay. The color refers to amarillo-dyed Spanish silk: a saturated, slightly red yellow with the satin finish of plant-and-mordant dye. The Spanish cousin of yellow.
