In this work, cognitive behaviour and electroencephalography (EEG) of 16 subjects applied colour matching and contrast colour matching to silk fabrics had been measured. The results showed that, the exogenous components P1 (100 ms) and P2 (200 ms) were mainly produced in the frontal, temporal, apical, and occipital regions, while the endogenous component P3 (300 ms) was mainly produced in the front-top area, the front-central area, the central-top area, and the top-pillow area. Regarding P1, the information transmission speed was faster than contrasting colours with matching process. Regarding P2, external and internal factors and their interactions significantly affected amplitude, whereas only interactions affected latency, and the interaction was stronger with colour matching. Regarding P3, colour matching type, involved brain area, and interactions had no significant effect on amplitude and latency. The information processing of same colour system in brain has shorter information processing time and faster information transmission. That indicated the EEG technology could provide objective visual cognitive aesthetic rules for silk fabric colour matching, and provide reference value for fabric manufacturers to timely understand consumers’ preference for fabric colour categories.
