墨乾掉後的那個顏色
墨乾在紙上是什麼樣子，這個字就拿去指那個樣子。顏料的名字就這樣變成色票上的名字：深、褐、帶一點紅，不是灰調的棕。
noun · C1
A dark brown colour with some red in it, like the brown that covers very old photographs.
深褐色
核心畫面
Picture a small sea animal that hides by squirting out a cloud of dark brown liquid. People once caught that liquid, dried it, and wrote and drew with it. Every use of sepia can be traced back to that one brown: the ink in the bottle, the animal it came from, the colour of the dried ink, and the old pictures that end up wearing that colour.
可以想成一隻墨魚在海裡噴出一團深褐色的墨，藉著那團霧躲起來。以前的人把那團墨撈起來、曬乾，拿來寫字和畫畫。sepia…更多收起
可以想成一隻墨魚在海裡噴出一團深褐色的墨，藉著那團霧躲起來。以前的人把那團墨撈起來、曬乾，拿來寫字和畫畫。sepia 的每個用法，就像都從這一團褐色長出來：瓶子裡的墨、噴墨的那隻生物、墨乾掉後的顏色，還有最後被染上這個顏色的老照片。From the word’s history
English borrowed sepia from Latin sepia, which meant cuttlefish, and that came from Ancient Greek sepia. So the word began as the name of the animal, then moved to its ink, and then to the colour of that ink.
英文的 sepia 借自拉丁文 sēpia，意思是「墨魚」，再往前是古希臘文 σηπία。所以這個字一開始是動物的名字，接著跑到牠的墨上，最後才變成那個顏色的名字。

From the picture
被染上這個顏色的舊照片
老相片因為藥劑和時間，整張泛成同一種褐。顏色的名字於是黏到照片上：現在說 a sepia photograph，聽的人腦中出現的不只是顏色，還有「很久以前」。
