Cool Zard

#a18515
Notes

Cool Zard (#A18515) 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 (48°, 77%, 36%) places it in the highly saturated band at a mid 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

Cool
adjective

Old English cōl, of low temperature — used as a color modifier as the complement to warm. Cool gray, cool blue: the optical impression of a slight blue-green shift, even within otherwise warm or neutral hues. Sits across the crisp, hushed, pale, and neutral buckets.

Zard
noun

The Persian word for yellow — used for the saffron-yellow of zard-čubeh (turmeric), the gold of Zoroastrian ritual fire, and the zard-i tu (your yellow — pallor) of Persian poetry. The color refers to fresh turmeric powder in a Persian kitchen: a saturated, slightly cool yellow with the dusty finish of plant pigment. The Iranian cousin of yellow.
