1. Space layout. This is the first priority. Elements should be placed reasonably and must not pile up to make people feel messy, so white space is very important.

2. Color matching. Color classification includes warm colors, neutral colors, and cool colors. Among them, the matching of warm and cold colors is very strict. Therefore, for the design of a plane or a series, it is best to determine the color first and set one color as the main color. Then other colors should match the main color. It is best not to use matching colors. Contrast colors - special designs are not an exception. And the number of main colors and auxiliary colors should not be too many, otherwise it will easily make people feel dazzled. Personally, I recommend two or three colors, with no more than five colors at most.

3. Illustrations and accessories must be reasonable. In addition to the color of the illustrations or shading not conflicting with the main color, they must not overwhelm the main color, otherwise it will put the cart before the horse.

4. Different designs require different attention. Please refer to other related professional books and materials. The space is limited, so I will only write down the three most important personal experiences to share with you!
