Persian blue has long served as a powerful hue in literature, conjuring vivid imagery and emotional depth throughout various texts. Writers employ it not only to describe objects but also to set a scene or mood. In one evocative passage, vases of Persian blue are so striking that their mere presence renders the character mute, imbuing the atmosphere with a sense of solemnity [1]. Other works highlight its rich history as a pigment—sometimes even identified with the delicate tone of woad flower [2]—with its deep shade achieved by layering indigo over madder [3]. The color's intense brilliance is further used to craft arresting visuals, as when a solitary palm appears dramatically against a blinding Persian blue background [4]. Moreover, the personal impact of the hue is noted when a character, unfamiliar with it, expresses wonder at its striking appearance [5], and its artistic versatility is underscored in practical applications where just a hint of Persian blue transforms a medium [6].
