The seems to be scarcity of scholarship when it comes to the significance of visual language in context to cartoons designed in the South African indigenous languages. As an attempt to bridge this gap, the aim of this research article is to investigate the literary significance of colour and size as visual language features in Mqapheli Mngadi�s editorial cartoons. The study is done literary through semiotic � stylistics to interpret the qualitatively �visuo � textually� examined data. The reader response theory is also adopted as the second literary theory to aid the analysis and account for what could be considered as the study�s possible limitations. The findings of the study demonstrate that colour and size, as visual language features, are used as one of the narrative techniques. This plays a significant stylistic role in assisting the cartoonist to paint complete pictures about the ideas he intends to convey. In addition to written words, these visual language techniques are essentially used to express ideas and build meaningful context.
