In the book "Take Me On" by Katie McGarry, the characters express their emotional states using colors as metaphors. One character relates their feelings of calmness and peace to the color green, suggesting a sense of tranquility in their life. This highlights how individuals often seek comfort in understanding their emotional landscape through relatable visuals.

Conversely, another character describes their feelings of sadness and struggle by identifying with the color blue. Despite their challenges, they assure their friend that they remain in a happier state, represented by the color yellow. This exchange emphasizes the varied emotional experiences people go through and how supportive relationships can exist even amid personal turmoil.
