köken: Learned borrowing from Koine Greek ἀπόχρωσις (apókhrōsis, “adding color”) + the modern suffix -ση (-si), from ἀπό- (apó-) + the root underlying χρώς (khrṓs, “complexion”) + -σις (-sis), with semantic loan from French coloration.
köken: Listed as borrowed from French nuance or English nuance. Some Japanese sources do not indicate a source language and only list the etymon form, as nuance, which is the format in these works to indicate an origin from English. Other references explicitly list both French and English as source languages, or just French. First cited to ふらんす物語 (Furansu Monogatari), a 1909 book by 永井荷風 (Nagai Kafū).
