Because the design angles of logos are different, the specific classification of logos is also different. But no matter how its angle changes, the logo remains unified internally. The following mainly analyzes the classification of logo design from two perspectives. 1. From the perspective of modeling, there are three categories of logos: one is concrete, the other is abstract, and the third is a combination of concrete and abstract. Concrete logos are designed based on specific images (mostly physical graphics) through various modifications, such as simplification, generalization, exaggeration, etc. Its advantage is that it expresses concrete characteristics intuitively and makes it clear at a glance. An abstract logo is a logo designed with dots, lines, surfaces, bodies and other modeling elements. It breaks through the shackles of concreteness and has a greater scope for modeling effects. It can produce strong visual stimulation, but is easy to understand. generate uncertainty. Such as the logo of Japan's Mitsubishi Corporation. The combination of concrete and abstract logos is the most common, because it combines the advantages of both concrete and abstract logo design types, making its expression effect particularly outstanding. 2. Starting from the basic components of signs, signs are divided into text signs, graphic signs, and combination signs that are a combination of words and figures. The so-called word mark is directly composed of words in Chinese, foreign languages ??or Chinese Pinyin, and is combined with the prefixes of Chinese Pinyin or foreign words. Mainly text-based, designed through text fonts, colors or deformations. A graphic logo literally means a graphic design logo, which is mainly a logo expressed through geometric patterns or pictographic patterns. It is also divided into three categories: concrete graphic logos, abstract graphic logos and logos that combine concrete abstraction. Convey meaning through graphics. To put it simply, a graphic and text combination logo is a combination of graphics and text, which concentrates the strengths of text logos and graphic logos and overcomes the shortcomings of both.
