The important function of packaging is to protect CTP, beautify products and transmit information. It is worth noting that for modern consumers, the latter two functions are more and more important, and designers pay more and more attention to packaging and decoration design. It is understood that in the process of packaging design, color, text, graphics and appearance are the four factors to be considered. In particular, the impact of color on consumers is often prior to the other three factors. Relevant data show that when human visual organs observe objects, color perception accounts for 80% in the first 20 seconds and modeling only accounts for 20%; after 2 minutes, color accounts for 60% and modeling 40%; after 5 minutes, both accounts for half. Therefore, in the decoration design of commodity packaging, we should pay special attention to the design and application of color, so as to improve the market share and competitiveness of commodities.
