Research On Visual Cognition Of Color Collocation Based On Silk Fabric

Color matching plays a decisive role in the innovative design of silk fabrics.This topic uses silk fabrics as a carrier,and uses three experimental methods: cognitive behavior,eye movement technology,and ERP technology to evaluate the color matching of the satin.The experiment adopted two matching methods: the same color collocation and the contrasting color collocation.Each group used two kinds of colors to explore the subjective and objective cognitive differences produced by the color matching of different area ratios.Cognitive behavioral methods were used to study the subjective cognition differences of color matching of different area ratios.The results showed that the change of color area ratio has a significant effect on females' aesthetic cognition under the two collocation methods.Males only have significant effects on the same color collocation;women score fluctuations more than men,and women have a more sensitive visual perception of color matching compared to men.When the difference in color area ratio is 60% to 80%,the score is higher,which is more in line with the public aesthetic.The difference between the two color areas ratio is 0,which is the most unsatisfactory.When paired with cool and warm colors,the collocation which warm color area is more than 50% gets higher aesthetic score.Through the eye movement technology,the change of the color area ratio has a significant effect on the subject's fixation time,the number of fixations,and the number of visual access;when the difference in the color area ratio is 80%,the visual attention is higher.When the difference in the color area ratio is 0,the visual attention is the lowest,consistent with the behavioral test results.Through ERP technology,the color area ratio has a significant influence on the early component(P1)and intermediate component(P2),while there was no significant effect on the late component(P3).In the early and intermediate stages,the electrode Pz was taken as an example.In the same color collocation,when the difference in the area ratio of rose redand pink was 0,the incubation period was the smallest and the amplitude was the largest.The incubation periods at P1 and P2 are 88.667 ms and 202.467 ms,respectively.The amplitudes at the P1 and P2 are: 2.819 uv and 4.426 uv,respectively.In contrasting color collocation,when the difference in the area ratio of blue and red were 0,the incubation period was the smallest and the amplitude was the largest.The incubation periods at the P1 and P2 periods are: 102.867 ms and 208.600 ms,respectively.The amplitudes at the P1 and P2 are 3.005 uv and 3.017 uv,respectively.It means that the stimulus information generated by these two kinds of collocations has the fastest transmission speed and the most intense visual stimuli.Combined with the results of behavioral tests and eye movement techniques,the aesthetic scores and visual attention of the two collocations are the lowest in the same collocation.It shows that the more beautiful the color match is,the easier it is to attract attention and produce stronger visual stimuli.In the late stage,the color area ratio has no significant effect on the late cognitive of the brain.
