When did Coca-Cola become a red symbol?

1979 changed its Chinese logo for the first time since it entered the China market. As one of the most valuable brands in the world, Coca-Cola's special symbols-special red and white English trademarks written in Spencer's font, red disks, curved bottles and wavy ribbon patterns, are well known. According to Bao, president of Coca-Cola (China) Beverage Co., Ltd., as early as a year ago, the headquarters of Coca-Cola Company began to consider updating the logo. The new logo is designed after investigating the major global markets including China, which is closer to consumers' lives. Therefore, Coca-Cola changed not only the logo, but also a way to communicate with consumers.
