In the movie Inside Out, the emotions are portrayed in different colors: yellow for joy, blue for sadness, purple for fear, red for anger and green for disgust.
These wild Lantanas proudly wear these emotions out in the open. And they group themselves into personality islands too!
Judging from the colors, these Lantanas must be an Optimistic bunch!
