To prompt customers to purchase products, retailers tend to use lighting to create the perfect atmosphere. However, lighting usually tends to modify the original color of products. In particular, under light-emitting diode (LED) lighting, colors might appear very different from their original forms. This study uses the concept of visual human factors and literature to find out five possible influence factors for color shift, representing the LED color temperature of the light source, the LED illuminance, and the color blackness, color saturation, color and color of the object. Waiting for five experimental variables, using the literature to confirm the LED color temperature and LED illumination level, the printing material selection is based on design experts and related units scholars and experts 4, of which four experts are experts A for professional field graphic design, expert B for Lighting interactive design experts, experts C for interior designers, experts D for the printing factory owner, jointly choose four common printing papers are as follows: Leni paper, ivory paper, Ange paper, coated paper. The color of the printed matter is in the four colors of red, yellow, blue and green in the NCS color ticket system. Using gray correlation analysis and sorting, the parameters of the most suitable LED lighting in four colors, as well as the color shift trend of the four colors, are studied, and the policy of the color shift compensation of the printed matter is determined according to the corresponding influence factors of the basic colors.
