Correlated colour temperature effects on perceived temperature,translucency,glossiness and roughness of traditional Jun porcelain,modulated by gender

Traditional Jun porcelain constitutes a significant cultural heritage, yet how lighting conditions affect its aesthetic perception remains underexplored. This study investigated the influence of correlated colour temperature (CCT) on multi-dimensional perception of Jun porcelain and examined the moderating role of gender. Using a THOUSLITE LED Cube lighting system, standardized Jun porcelain specimens with Lilac Purple glaze were illuminated under eight CCT conditions (2700 K to 6000 K) at constant 150 lx illumination, with spectral characteristics verified using a THOUSLITE FS spectroradiometer. Thirty participants (15 males and 15 females) evaluated five perceptual dimensions (glossiness, translucency, roughness, temperature and relief perception) of the specimens. Results revealed significant linear relationships between CCT and four dimensions, with higher CCTs enhancing perceived glossiness and translucency while reducing perceived roughness and temperature. Relief perception exhibited negligible sensitivity to CCT. Gender significantly modulated these relationships, with females showing greater sensitivity to CCT variations in perceiving glossiness, translucency and temperature, while males demonstrated stronger responses in roughness evaluation. These findings demonstrate predictable, linear CCT effects on Jun porcelain aesthetic qualities with dimension-specific and gender-based perceptual differences. This study advances understanding of lighting-material perception interactions and provides targeted lighting strategies for culturally authentic ceramic exhibition design.
