Meaning‐making with colour in multimodal texts: an 11‐year‐old student's purposeful ‘doing’

Colour, a visual element of art and design, is a semiotic mode that is used strategically by sign‐makers to communicate meaning. Understanding the meaning‐making potential of colour can enhance students’ understanding, appreciation, interpretation and composition of multimodal texts. This article features a case study of Anya, an 11‐year‐old student who participated in a classroom‐based research project that explored developing student visual meaning‐making skills and competencies by focusing specifically on a selection of visual elements of art and design in picture books and graphic novels. Excerpts from Anya's interview about her multimodal print text revealed that her intentional use of colour was affected by her participation in the learning opportunities afforded during the explorative study that included overt instruction about making meaning with colour. The semiotic analysis of Anya's use of colour in her multimodal text included a consideration of how the various distinctive features of colour were evident in her work. The article concludes with a discussion of pedagogical and assessment issues associated with teaching students about colour and other visual elements of art and design.
