When you're looking for meaning, the better way to think of this is: "Why aren't the curtains another colour?"
Because a character walking into a room with blue curtains is totally different to a character walking into a room with red velvet curtains, which is totally different to a character walking into a room with a corn-themed curtains.
In each example, the curtains give a different perspective of the room, which changes the way we see the character. A depressed character is unlikely to own sparkly pink curtains. The author has included that the curtains are blue, because the blue reflects the state of the character.
If the character did own sparkly pink curtains (assuming hypothetically, that we pretend they exist outside the words of the author), it is unlikely that the author would mention it, because it doesn't add anything to our understanding of the character, or their world (unless it's being used as an obvious contrast).
If you have a depressed character, it's fairly safe to assume that blue was chosen because it adds to that aesthetic.
