Graphic design and ppt design are cross-related. Ppt, graphic design and behavior design sometimes cross together. For example, some advertising posters are interactive, and only interactive behavior can reflect the meaning of graphic posters.

Graphic designers may use their professional skills in typography, visual arts, layout, computer software and so on to achieve the purpose of creative planning. Graphic design can usually refer to the process of making (designing) and the final finished work. Common uses of graphic design include logos, publications, print advertisements, posters, billboards, graphic elements of websites, logos and product packaging.

for example, product packaging may include trademarks or other works of art, arranged texts and pure design elements, such as images with uniform styles, shapes, sizes and colors. Combination is one of the most important characteristics of graphic design, especially when the product uses pre-existing materials or multiple elements.

In the physics class of middle school, we may have done the experiment of prism. After passing through the prism, the white light is decomposed into a color spectrum with gradual transition, and the colors are red, orange, yellow, green, cyan, blue and purple in turn, which is the visible spectrum. Among them, the human eye is most sensitive to red, green and blue, and the human eye is like a system of three-color receivers.

most colors can be produced by combining red, green and blue in different proportions. Similarly, most monochromatic light can be decomposed into three colors: red, green and blue. This is the most basic principle of colorimetry, that is, the principle of three primary colors. The three primary colors are independent of each other, and none of them can be combined with the other two colors. Red, green and blue are three primary colors, and these three colors have the widest range of colors.
