the Cape jasmine, Gardenia jasminoides · short for 梔子色 (kuchinashi-iro): a gold color as of the fruit of a Cape jasmine; a style of layering garments with yellow on both front and back
köken: Possibly an extension of 口無し (kuchinashi, literally “without a mouth”), from the absence of the fruit's cleaves even when ripe. The kanji spelling is an orthographic borrowing from Chinese 梔子 /栀子 (zhīzi).
