Tracer Ireland

#66a43c
Notes

Tracer Ireland (#66A43C) is a true lime 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 (96°, 46%, 44%) 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

Tracer
adjective

Old French tracier, to trace — sharing root with English trace and track. As a color modifier, tracer implies a saturated-and-streak-of-light quality, the bright color of military-tracer-round and long-exposure-photography light-trail visual streak. Sits at the bright-and-active end of the grid, parallel to flashing and streaking in usage.

Ireland
noun

The Emerald Isle — and the saturated deep green of Irish countryside, the cathair (capital green) of Dublin, and the Connacht shamrock symbol. Ireland refers to a County Kerry hillside in May: a saturated, slightly cool deep green with the matte finish of well-watered Atlantic-coast grass.
