This study examines Thangka's color contrast mechanism achieving dynamic equilibrium through cold-warm interactions. Rooted in mineral pigments and traditional philosophy, its visual tension is mediated by complementary hues and compositional balance, integrating visual psychology, materials science, and computer-aided analysis. The interdisciplinary framework reveals how empirical mastery of chromatic opposition, purity gradients, and spatial cognition converges into perceptual harmony. Modern applications drive digital innovation and cross-media adaptations, offering methodological insights for traditional craft modernization while enriching universal color theory with culturally specific paradigms.
