Starched Ki-iro

#ac9b2c
Notes

Starched Ki-iro (#AC9B2C) is a true amber with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (52°, 59%, 42%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Starched
adjective

Old English stercan, to stiffen — past-participle of starch. As a color modifier, starched implies a clear-and-stiff-and-formal quality, the crisp color of Edwardian-period formal-evening-shirt-and-collar starched-and-pressed dress-attire. Sits at the crisp-and-finished end of the grid, parallel to pressed and ironed in usage.

Ki-iro
noun

The Japanese word for yellow — built from ki (yellow) and iro (color). Used in the warm palette of ukiyo-e woodblock prints, kintsugi-repaired ceramics, and the gold-leafed wallpaper of Heian-period palaces. The color refers to ki-iro-painted byōbu folding screens: a saturated, slightly cool pure yellow with the matte finish of mineral-pigment-on-paper. The Japanese cousin of yellow.
