This isn't the only book to use a different color scheme. I know at least some of them have a light grey (neutral) and a dark grey (sad). This one has the light grey that equates to some the blue in some books, so the blue here, equates to the green in some books. At least that is my experience.

I should start making more notes on that subject. I can use that information.
