Distribution of 'mood' color choice in healthy, anxious and depressed individuals. 41 (39%) healthy subjects, 76 (70%) anxious and 87 (79%) depressed volunteers related color to their mood. Compared with healthy volunteers, the choice of 'Yellow 14' is significantly reduced in both depressed (p < 0.001) and anxious (p = 0.001) individuals (Fisher's Exact test). In contrast, compared with healthy volunteers, the choice of 'Grey 36' is significantly increased in depressed (p = 0.020) individuals but not in those with anxiety (p = 0.134) (Fisher's Exact test). Volunteers not choosing a color to describe their mood have been omitted from the figure.
