This work only uses the four pure colors of CMYK. All the colors presented in the eyes of the audience are mixed in the audience's visual system. I create perceptual visual works in a purely rational way. Sensibility can make us feel nature, but we cannot understand and use nature by this way. Through rationality, people have created the greatest faith and power in human history, science. Therefore, I use rational thinking to create works of art through experimental scientific methods.
