When I look at season 4 for what it is. I came to the conclusion that Raven is an enneagram 4. Remember she is kind of Moody and keeps her feelings for the most part to herself. Then you got different colors which represents her emotions being unstable due to her holding it in. When she wore white and revert to her age that is her integrating to a 1 which is emotional balance and the real Raven comes out and show her true feelings but with control.
