Don't we all remember those dreaded times when we had to read books for class (that part wasn't so bad) and then the teacher would dwell hours on one particular paragraph, literally analyzing it to death. Said teacher also managed to bore all students to death during those hours. If you ask me it's teachers like these who transform potential book lovers into book avoiders. Not to say that happened to me, but in all honesty, as much as I love reading, hold one of the books we had to read for class in front of my nose and see me doing a very good impression of the Scream mask. I'm not joking.
Authors may put a whole lot of hidden meaning into tiny little details that the reader must excavate to fully appreciate the story. Or do they? Some do, others don't. Some authors love to convey their messages through "blue curtains", others just give thought to setting the scene and oddly enough blue curtains go wonderfully well with the colorful vintage furniture in our hero's humble abode. In the end it's always the details that make the book work - from the elaborate descriptions of a place to the detailed descriptions of a character's thoughts, from the inconspicuous to the accidental straight to the obvious. A well-wrought map that composes the story.
And maybe it's just me, but as much as I love how details can eg unravel a mystery in a book - and I'm saying this as a reader and a writer - I'm not much for taking a story apart word by word. If you must, feel free to do so, but let me tell you this: Reading is about more than the forest. It's about the trees that make the forest the place it is. It's not about each and every pine needle on the forest's floor. Still the pine trees are definitely important. I obviously love analogies like this. Still, those curtains are blue for no reason.
Fun fact: While you refer to a person being blue when they are sad in the English language, if you refer to someone as blue in German, that person would be drunk! That opens up a whole new perspective for our blue curtained hero.
