Through long-term life experience, people have consciously or unconsciously formed the ability to judge and feel objects based on colors. Different colors give people different visual and psychological feelings. It will not only enhance the aesthetic pleasure of consumers, but also stimulate consumers' judgment and confidence in purchasing, enrich their imagination, and cultivate the minds of customers.

For this reason, black and white lose their color appearance compared with other colors, forming their own unique achromatic properties. This article talks about color from the perspective of packaging design. It is not a discussion of the so-called physics of optics, electromagnetic waves, and wavelengths. It focuses on the hue, brightness, purity, and color psychology of colors based on the theoretical basis of design chromatics. Research on aspects of the problem. In the ocean of commodities, packaging design is constantly changing methods, innovating forms, and shaping individual characteristics, with particular emphasis on the attributes of colors and the use of colors. The attributes of color are not static, and the changes among the elements provide a rich space for the contrast and use of harmony in the design of colors.
