In fact, the design of Douyin’s musical note logo is a frame captured from a shaking video after being subjected to radio wave interference. It closely follows the "shaking" theme of the brand, and then uses red and blue primary colors to strengthen the attributes of the video industry, maximizing the integration of "shaking" into the user's visual senses, thereby establishing the user's association with the brand. The logo design background of the App is black, which is intended for an immersive experience. At the same time, the black background makes the App visually penetrating on the mobile phone. In addition, the Douyin logo is also more malleable. This "shaking" method can be used in all dynamic environments. Through the "shaking" effect, any image can establish an association with the brand.
