Each circle represents an individual. The thin border around each circle represents what you notice first (readily detectable characteristics). The inside of each circle underlines all deep-level characteristics someone has (e.g., personality, attitudes, education, perspectives, skills, etc.). Anyone is free to interpret the meaning of each color, because we all have different perceptions.

Just a happy girl waving, wearing a skirt, sandals, and a shirt with a heart on it. The way I built her in Inkscape, she's much like a puppet. So you can ungroup the different parts of the drawing and rotate them and group them back together if you like.
