Warm Chéng

#8d3703
Notes

Warm Chéng (#8D3703) is a deep orange 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 (23°, 96%, 28%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Warm
adjective

Old English wearm, of moderate heat — used as a color modifier since the medieval period for hues that read as containing red, orange, or yellow undertones. Warm gray, warm white: not necessarily a temperature, but the optical impression of a slight red-orange shift. Sits across the crisp and neutral buckets.

Chéng
noun

The Chinese word for orange — both the fruit and the color, used in classical poetry for the autumn ripening of citrus orchards in Fujian and Guangdong. The color refers to a ripe Chinese mandarin: a saturated, slightly red orange with the satin finish of citrus rind. Slightly warmer than tangerine, the Chinese cousin of mikan and daidai.
