Don’t You Like the Green of A? is based on the correspondences between letters and colors specific to Joan Mitchell’s synesthesia––a condition that Henricks happens to share with her. Synesthesia is a neurological syndrome in which perception by one sense automatically triggers a perception in one of the other senses. This connectivity between senses may be manifested in different ways. For example, in grapheme-colour synaesthesia, numbers or letters are associated with colors; in music-color synesthesia, people perceive color by hearing a sound or music.
