This paper examines the integral role of set design in children’s theatre, specifically exploring the infusion of colour from a child’s viewpoint to enrich their theatrical encounters. Informed by Schonmann’s and Weincek’s insights into children’s theatre and set design, and grounded in the experiential value of artistic methodology, this study employs a representational art concept to craft set designs that resonate with the sensibilities of young audiences. Through a focus group discussion with Ghanaian children aged eight to thirteen, a preference for polychromatic colour schemes emerged. Harnessing these preferences, the research develops a set design tailored to elevate the overall theatrical experience for children. Employing a formalistic approach, the study describes the incorporation of elements in the design and interprets the significance of colours. By understanding children’s colour perspectives, this research aims to convey their ideas, express emotions, and facilitate effective communication. Ultimately, the study empowers children as active participants in the theatrical experience, fostering interpretation, interaction, and questioning on their own terms.
