Most of China's Changyu wine and Shuanghui sausages as well as CJ's meat product packaging are expressed in this form. This form of packaging is also common in Japan, South Korea and Taiwan. The visual effect it displays is bright, simple, gentle and elegant. (2) The contrast between light and heavy colors (or dark and light contrast) is also one of the important reproduction techniques in the use of packaging colors. This kind of contrast between light and heavy is often used to set off a dignified and profound theme pattern on a light and elegant background, or in a dignified and profound theme pattern (mostly color block patterns are the focus). Show the light and elegant packaging theme and name, as well as trademarks or slogans, etc. Conversely, a large area of ??dignified and deep pigment is used as the base. In addition, use light and elegant colors or focus on a certain color block or fully decorate some patterns. In this kind of contrast between light and heavy, general pigments have harmonious color contrast and cold and warm color contrast.

This is not only a combination of points and surfaces, but also a contrast between large and small, and occasionally from point to And the contrast of gradual transition.

Packaging design that reflects product characteristics.
