The elements of logo design are: name, pattern, and color.

1. Name An excellent and perfect trademark must not only have a beautiful and distinctive pattern, but also have a distinctive, loud and catchy name. The brand name not only affects the future circulation and dissemination of goods in the market, but also determines the entire design process and effect of the trademark. If the trademark has a good name, it can give the graphic designer more advantages and flexibility, and the designer may be more creative. On the contrary, it will bring certain difficulties and limitations, and will also affect the expressiveness of the artistic image.

2. The names of countries, national flags, national emblems, military flags, medals, or patterns that are identical or similar to them cannot be used as trademark patterns. Some special signs stipulated by international and domestic regulations, such as the red "cross", civil aviation signs, railway emblems, etc., cannot be used as trademark patterns. In addition, when choosing animal images as trademark patterns, you should pay attention to the likes and taboos of different ethnic groups and countries towards various animals.

3. Color Color is one of the three basic elements of form (shape, color, and quality). The commonly used colors for logos are the three primary colors (red, yellow, and blue). These three colors have relatively high purity, are relatively bright, and are more eye-catching. Color is a basic topic that must be studied in the discipline of industrial design. Color research involves many disciplines such as physics, physiology, psychology, aesthetics and art theory.

Reference materials: Logo design must first consider and discuss several key points: 1. Recognition: the logo must have a unique personality, be easy for the public to recognize and remember, and leave a good and deep impression, but relatively speaking , If the Dalian logo is similar to others, it looks familiar, has no characteristics and a vague design, it will definitely not leave an impression on people. 2. Originality: Design is valuable in having original ideas and shapes, and the same is true for the Dalian logo. The original Dalian logo will definitely leave a unique impression in the public's mind and can stand the test of time. Originality can be created out of nothing, or creativity can be added to tradition and daily life to bring forth the new. 3. Contemporary nature: Dalian’s logo cannot be out of touch with the times, giving people the impression of being outdated and backward. The Dalian logo of a modern enterprise must, of course, be modern and rich in historical tradition.
