Hold one colour in mind: a pale, washed-out gold, closer to straw or to light wood than to bright yellow. Everything else is that colour being pointed at different things. Point it at hair and you get blond hair; point it at the person wearing that hair and he is blond, or she is a blond; point it at the colour on a card in a salon and you get six shades of blond. One pale gold, aimed in different directions.
Borrowed from Middle French blond, going back to a Frankish word *blund meaning a mixed colour between golden and light brown, from a Germanic root related to blend. The mixed, in-between quality in the old word matches the modern colour, which is never a pure bright yellow.
可以想成從中世紀法文 blond 借進英文，再往前追到一個法蘭克語的字 *blund，意思大約是「介於金色和淺棕之間的混色」，和 blend（混合）同一個老根。那個「混著、說不準」的味道，正好對上今天這個顏色：它從來不是純粹的亮黃，而是偏淡、帶點別的東西在裡面。

Three branches
淡金色這個顏色
最靠近核心畫面的一組：字直接指著顏色，不管它長在什麼東西上面。
adjective · A2
Pale golden yellow in colour. It is used most often about hair, and also about other things with that light, washed-out yellow shade, such as pale wood. Blond and blonde are two spellings of the same word.
金色的；淡金色的
有這種頭髮的人
把顏色從頭髮身上再往外推一步，指向頂著這頭髮的那個人。英文很習慣這樣做，brunette、redhead 也是同一種走法。
adjective · A2
Used about a person, especially a man or boy, who has pale yellow hair. Writers usually spell it blond with no e for a man and blonde with an e for a woman, though many people now use blond for anyone.
（人）金髮的
從刻板印象長出來的貶義
這一支不是顏色再往外指，而是社會偏見接在顏色後面長出來的。畫面已經離開頭髮，落到「這個人不聰明」的評價上，所以它和上面兩組的性質不一樣。
adjective · B2
Used to say that someone is slow or silly, from an old idea that people with pale yellow hair are not clever. It is an insult about the person, and many people hear it as offensive even when it is meant as a joke.
笨的（帶刻板印象的貶意）
