One way to see true-blue: cloth so deeply that no amount of washing pulls the colour out. True says the colour goes all the way through rather than sitting on the surface. So both uses of the word are really about something that is still the same after time and trouble have worked on it — a friend, a fan, a voter. The praise is never for how warm someone is today; it is for not .
可以想成一塊染得很透的藍布：洗過、曬過，顏色還是那個顏色。true 的意思是「染進去的，不是表面刷一層」。所以這個詞的兩種用法，說的都是同一件事——時間和麻煩都試過了，這個人還在原地。它誇的從來不是「他今天對你多熱情」，而是「他不會褪色」。
