In the era of digital media, dynamic graphics have become the core carrier of information communication, and its color presentation and rhythm control directly affect the audience's cognitive efficiency and emotional experience. Currently, the visual communication field is facing the double challenges of high information density and visual fatigue, and the traditional static color theory is difficult to adapt to the perceptual needs of continuous changes in space and time in dynamic scenes. Along with the development of interactive technology, there is an urgent need to establish a systematic design paradigm for color emotion regulation and visual motion guidance. Therefore, this paper discusses the color rhythm generation mechanism and visual guidance optimization path of dynamic graphics, in the hope of providing quantifiable aesthetic control basis for information visualization design in multi-screen interactive environment.
