Warm Yānhuī

#2b0710
Notes

Warm Yānhuī (#2B0710) is a deep red 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 (345°, 72%, 10%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary teal. 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.

Yānhuī
noun

Chinese 烟灰, smoke-gray — the formal Chinese color name for the deep-cool-gray of yānmò (smoke-ink) calligraphy ink, derived from pine-soot combustion. Yānhuī color refers to a freshly mixed yānmò ink-and-water dilution on a Song-dynasty xuān-paper sheet: a dark gray with the matte finish of pine-soot-and-glue ink on absorbent hand-finished Chinese rice-paper.
