Designer: The logo of China Unicom was designed by Li, president of Tianda Advertising Company. 2. Composition and symbol: (1) overall design. The company logo of China Unicom evolved from the ancient auspicious pattern "Pan Chang" in China. The line running through the ring road symbolizes that China Unicom, as a modern telecom enterprise, is orderly, swift and smooth, and the cause of Unicom will never end and last forever. (2) pattern design. Logo modeling has two obvious "hearts" connected from top to bottom, which vividly shows the service tenet of China Unicom, always caring for users and connecting with users. (3) color design. Red represents enthusiasm, boldness and vitality, giving people a strong sense of visual impact; Black ink is a symbol of nobility and stability. The combination of red and black has the visual beauty of stability, harmony and tension. (4) Letter design. The red double "I" is the crowning touch, which not only highlights the brand spirit of "let everything be freely connected" when they communicate at any time and anywhere, but also cleverly forms an auspicious spike shape in the vertical combination, which strengthens the image of Unicom in the hearts of customers.
