With the deep integration of mobile internet and the "Smart Tourism" policy, travel mobile apps have become core tools for users' pre-trip planning, in-trip services, and post-trip sharing. As one of the core elements of user experience design, interface color design directly affects users' visual perception, emotional experience, and usage behavior. Based on the theories of color psychology and human-computer interaction, this paper, grounded in user experience theory, conducts an in-depth analysis of the characteristics and color needs of travel app users, as well as the current status of color design in travel app interfaces. Furthermore, this paper explores color design methods for travel app interfaces from the dimensions of function, emotion, scenario, and dynamic interaction, aiming to provide theoretical references and practical guidance for enhancing the interface usability and aesthetic value of travel apps.
