Tracer Helichrysum

#999c09
Notes

Tracer Helichrysum (#999C09) is a deep 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 (61°, 89%, 32%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

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.

Helichrysum
noun

The genus Helichrysum — Mediterranean composite-family plants whose dried yellow flower bracts retain their color for years (also called strawflower). The color refers to dried Helichrysum bracts in a winter bouquet: a soft, slightly muted dry yellow with the matte papery finish of preserved flower.

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.
