As a core mechanism of human visual cognition, color perception plays a key role in the digital narrative environment.By analyzing the differences in psychological effects between warm colors (Vermilion Red #FF6B35, Amber Orange #FFA500,Golden Yellow #FFD700) and cool colors (Indigo #4B0082, Teal #20B2AA, Violet #8A2BE2), this paper explores the emotional guiding function of high-saturation colors in interactive dynamic interfaces. Using the HSB color model and the principle of visual hierarchy construction, an interactive dynamic graphics system is designed to realize the recombination and presentation of narrative content. Experimental verification shows that the interactive design based on color perception can effectively improve users' narrative participation and emotional resonance intensity, providing a new design path for digital media narrative.
