## 3 Methodology
### Method
Participants were asked to rate the extent to which specific color combinations influenced their feelings of comfort, well-being, and overall satisfaction with the urban environment. Demographic Information: In addition to the perceptual and preference data, participants were requested to provide demographic information, including age, gender,profession, and the duration of their residence or involvement with marine cities. This demographic data enriched our understanding of how color preferences and perceptions might vary across different demographic groups. Fieldwork and Case Study Area: In conjunction with the questionnaire, fieldwork was conducted within Zhuhai Shijingshan Park, which was selected as our case study area due to its alignment with the research objectives and its representation of a marine city. During the fieldwork, we performed visual observations and measurements to meticulously document color elements present in the park. Additionally, contextual information regarding the integration of these color elements into the urban landscape was meticulously recorded. (3) Data Analysis:  
The data collected through the questionnaire were subjected to descriptive statistics and correlation analysis to explore the relationship between color preferences and psychological needs. Descriptive Statistics: Descriptive statistics were employed to summarize and describe key features of the collected data. Measures, such as the mean, median, standard deviation, and frequency distribution, were calculated to provide a quantitative overview of participants' responses. Correlation Analysis: Correlation analysis was conducted to examine the strength and direction of the relationship between color preferences and the various psychological needs identified in the questionnaire. This analysis aimed to identify significant correlations between specific colors and psychological responses, shedding light on the associations between color and human psychological well-being. The analysis yielded several findings that significantly contribute to the understanding of urban color design in marine cities:  
Strong Correlations: The data revealed strong positive correlations between certain color preferences and specific psychological needs. For instance, participants consistently associated cool ocean blues and refreshing coastal greens with feelings of calmness and relaxation. These color preferences were also linked to heightened perceptions of well-being and comfort in urban marine environments. Demographic Variations: An intriguing aspect of findings was the presence of demographic variations in color preferences and their associated psychological responses. For example, younger participants tended to favor vibrant and energetic color palettes, while older participants leaned toward more serene and subdued hues. These distinctions offer valuable insights for tailoring color designs to different demographic groups within marine cities. Design Implications: The findings hold practical implications for sustainable design in marine cities. By recognizing the strong correlation between specific color choices and enhanced psychological well-being, urban planners and designers can strategically employ color palettes that foster positive psychological responses, contributing to the overall livability and vibrancy of marine urban environments.
