The Valley of Astonishment had the intention of taking every spectator on his or her own experience of the tale of synesthesia through a fresh perspective. The semi-formal costumes scheme involved only plain, solid colors, with no bold patterns or designs. Shades of black, white and blue were prominent. The very slight costume changes with character transitions and consistency of plain costumes seem like techniques used to avoid audience distraction and used to keep spectator attention and thought on the mind-driven journey of the story. White lab coats were worn when the actors represented doctors and slight additions of layers were used to change the identities of the characters. The simplicity that was kept with costume design was used so that spectators would use their imagination, starting from a blank canvas rather than being moved by details that are physically apparent, to experience the vivid images, details, feelings and senses of the story.
