The rapid growth of tourism has led to the transformation of numerous traditional dwellings in Yunnan into commercial lodgings, presenting a challenge to the preservation and inheritance of traditional culture. However, the existing renovation practices lack scientific data support and rely heavily on architects’ subjective designs. Thus, finding a scientific and stable approach to maintain the traditional residential characteristics becomes crucial. This study focuses on the renovation of Wenzhi villagers’ residences in Yunnan as a case study. It employs the innovative AHP-QFD design methodology to explore a more scientific and objective method for preserving and promoting the features of traditional dwellings in commercial renovations. Initially, the study assigns weights to the commercial renovation objectives—local traditional features, architectural functions, sustainability, and comfort—using the hierarchical analysis method (AHP). Subsequently, specific design features are derived from transformation requirements through interviews and questionnaires with residents, tourists, government officials, and experts. The innovation of this research lies in the application of AHP and QFD models to the innovative design of commercial renovations for traditional dwellings in Yunnan, resulting in a set of systematic and scientifically supported decision-making methods for renovating and preserving traditional buildings in the region. The study’s findings reveal that building geometry and dimensions, skilled traditional craftsmanship, and flexible and expandable solutions carry the highest weight in design. The application of the AHP-QFD model in commercial transformation design effectively balances the preservation of traditional culture and the pursuit of commercial value. It offers a feasible and innovative design solution for commercial transformations of traditional houses in the Yunnan region, ensuring the preservation of cultural heritage while enhancing commercial appeal.

In this paper, we take the images of Miao costumes as the research object, construct the color system of Miao costumes based on the aesthetics perspective, and take the color migration as the research content to realize the visualization and innovative design of Miao costumes. Firstly, typical Miao dress images are obtained by digital acquisition. Then, RGB and HSL color modes are used to extract the colors and mine the color association rules of Miao dresses to construct the color system of Miao dresses. Then, an image segmentation method based on the color system of Miao costumes is proposed to achieve color migration between the color regions of decorative patterns. Finally, the patterns in the dataset of Miao costumes in Qiandongnan are extracted. Based on the classification study, a systematic and in-depth analysis of the color performance of the pattern patterns is conducted to clarify their artistic and aesthetic forms. It is found that the colors of Qiandongnan Miao costume patterns are mostly high-purity and high-brightness colors, of which high-purity colors (7-10) account for the highest proportion, including 16 colors such as earth red, grape purple, pink, and big red, accounting for about 56.5% of the total. The proportion of high brightness colors (7-10) in the colors is the highest, including 13 colors such as beige, goose yellow, grape purple, peach red, etc., accounting for 68.1%. It can be seen from the use of hues in the dress patterns of the Miao people in Qiandongnan that they will match the colors of the patterns according to the “five colors” and highlight a certain color as the dominant color according to the theme. The whole is complete, full of variegated and strong ethnic flavor.
