What are the requirements for corporate slogans? For corporate publicity slogans, the most direct way is to plan and design by limiting font, color and font size. Here we analyze the reason through a simple legend. First of all, limiting fonts to no more than three standard font designs is the primary demand of all designers. Generally speaking, in font design and logo design, no more than three fonts can be used. Because the font occupies a very large area in the design, the font itself and the meaning it carries need to be considered in the design. Second, designers with different design style standards design different product styles, but all design styles are unified. The design style of standard characters is also designed by designers, which is very in line with the style of the product itself. If design is a moderate aesthetic [4], it is very appropriate.
