Abstract: Kazakh harness decoration pattern is an important part of Kazakh culture, which contains unique national characteristics and artistic charm. This article took the decorative patterns of Kazakh horse harnesses as the research object, systematically analyzed their artistic characteristics, and extracted the typical pattern factors and color factors by using the user perceptual semantic evaluation experiment to analyze the commonalities and characteristics of consumers' emotional preferences for the decorative patterns of Kazakh horse harnesses. Innovative derivative patterns were applied to the design of modern leather goods to make the products conform to modern aesthetic cognition and at the same time have ethnic characteristics and cultural connotations. This work not only favors the inheritance and innovation of Kazakh patterns, but also provides research ideas and practical methods for the innovative application of other ethnic patterns in the field of leather goods.
