If an impartial member is retelling the story, it's possible that the narration is more reliable. The second-person point of view is by far the least common, but when used correctly, it can have a great effect.
I had mentioned blue earlier as an example because of its many implications. But all the descriptors can find a way back to the indispensable form.
Thus, this can suggest that all things are inter-related to one necessary core.
Another example: Though the only pronoun that appears in the sentence is "they," which implies a third-person point of view, this novel actually uses the first-person point of view, and the subject doesn't actually appear in the sentence.
Also, make sure you take samples from multiple points in the text. While good ol' Stephen King here begins his novel in the first-person point of view, the story is in three parts, and the middle part is in the third-person point of view. But don't worry; by paying attention to the pronouns, you can identify narrative voice easily. There are important considerations to be made when deciding on your point of view.
