New buildings continue to be constructed in historic districts as urbanization accelerates. This leads to incongruities between historic and modern buildings, as well as degradation of the historic landscape. As a means of resolving these problems, this study uses the expert scoring method to solicit opinions from relevant experts through anonymous methods for architectural samples and establishes two groups of architectural images that have been screened for objective color attribute analysis. Comparing the architectural color codes on site was conducted using the Chinese Architectural Color Card based on the Munsell color system. Furthermore, questionnaires were used to measure the differences in visual comfort between different building types by asking the subjects to rate architectural colors when viewing architectural images. This study will also combine the advantages of measurement and analysis of objective objects with the study of human perceptual experience in order to enhance its practicality. In general, the buildings in the West Nanjing Road Historic Landscape District are painted in warm yellow, and the public is aware of its comforting color. Both historical and modern buildings in the historic district are mostly of medium and high brightness, and both use low-purity colors for the main body of their structures. Despite some differences between people of different genders, ages, and literacy levels, all of them agree on the main tone of warm yellow color in architectural colors.

To enhance the stability of wood and decrease restrictions on its use in the furniture industry, hydrophobic modification can be employed to confer waterproof, anti-fouling, and self-cleaning properties. The present study outlines the preparation of silica sol using the sol–gel method, followed by impregnation and chemical vapor deposition methods to modify the sol. After grafting 1H,1H,2H,2H-perfluoro-decyl trichlorosilane (FDTS), hydrophobic and superhydrophobic properties were imparted to the wood substrate. To explore the correlation between the surface properties of the wood substrate and superhydrophobic coatings, the densities, porosities, and surface roughness of various tree species were compared. The results showed that the sol–gel method successfully constructed hydrophobic coatings on different wood substrates, with six samples (poplar, elm, toon wood, paulownia, ashtree, and black walnut) achieving superhydrophobic surfaces, with densities ranging from 0.386 to 0.794 g/cm³, porosity ranging from 13.66 to 42.36%, roughness ranging from 4.660 to 11.244 um, and maximum water contact angle of 165.2°. Whereas beech and rosewood only reach the hydrophobic surface. Although the coatings demonstrated good resistance to water, pollutants, self-cleaning, and chemical agents, further improvements are necessary to enhance mechanical wear resistance.
