This study analysed the characteristics of perceptual similarity judgements for colour-category boundary pairs in a digital display environment. Ten adjacent colour pairs on the Munsell hue circle were selected and a repeated-measures experiment was conducted in which participants rated, on a 7-point scale, the similarity of the right-hand stimulus relative to the left-hand stimulus. The Pearson correlation coefficient between Session 1 and Session 2 (r = .796) and the ICC (.80) indicated high repeat reliability and the paired-samples t-test also showed no significant difference. ANOVAs revealed statistically significant differences in similarity judgements across colour pairs for Session 1, Session 2, and their combined mean, supporting systematic effects of category boundaries. The regression analysis on lightness difference found no significant effect, as all colour pairs were controlled for lightness. Pairs such as Y–GY, B–PB, and GY–G consistently exhibited lower similarity scores, while P–RP and G–BG were perceived as more similar. This study provides evidence that perceptual sensitivity at colour-category boundaries exerts a systematic influence on colour perception. These results imply that boundary-based colour choices can impact user experience by unintentionally increasing or decreasing perceived similarity in digital design contexts.
