We first read this book in the 90s. I seem to recall the setting begins in a village. All of the doors as we go along are green(?), but then we see one that is painted purple. The female character who lives here is odd, eccentric compared to the lives of the rest of the villagers.

She and a group of friends go off on a quest, leaving the village. The title might include something about Book or Green, but then again, it might not. This was included as part of Sonlight Homeschool curriculum.
