## 3 Methodology
### Survey Analysis  
On the premise of not disturbing the people in Zhuhai Shijingshan Park and Shijingshan Park Square, they were photographed and analyzed, and people around were talked to, to understand their views on the colors of the square, and a questionnaire survey was conducted to find out the problem areas, from which 100 questionnaires were distributed in Square (92 were validly returned). The selection of 92 valid responses was based on a careful consideration of statistical power and the desire to provide meaningful insights. There were eight unqualified questionnaires due to incomplete answers and other reasons. This sample size was deemed appropriate for our research objectives, as it allowed for a robust statistical analysis and the detection of significant correlations between color preferences and psychological needs. Additionally, this research applied rigorous quality-control measures to ensure the validity and reliability of the responses, further enhancing the credibility of the research survey results. The basic information of the survey respondents included where the respondents came from and their age; the survey was mainly about the general impression of the Square and the general feeling of the colors of the urban landscape; the colors of the garden elements were assessed in detail, taking Shijingshan Park Square as an example. To comprehensively capture visitor preferences and contextual insights, our research employed a multifaceted data collection approach. Firstly, we administered surveys to visitors, both in situ and through online channels, with the aim of soliciting their opinions, preferences, and emotional responses concerning the color palette prevalent in the urban milieu. To ensure the representativeness of our sample, this research employed a stratified sampling technique. This involved categorizing potential respondents into distinct demographic groups, including age, gender, occupation, and residence location. Within each stratum, participants were randomly selected to participate in the survey. The survey aimed for a sample size that would provide statistically significant results while ensuring diversity. The rationale behind this diversity was to capture a comprehensive spectrum of perspectives on urban color design, ensuring that these research findings are robust and applicable across different demographic segments. These meticulously constructed questionnaires are thoughtfully designed to elicit specific feedback pertaining to the visual, psychological, behavioral, and spiritual dimensions of their color-related experiences. Secondly, we executed extensive field surveys across various marine cities, exemplified by our focal case study, Zhuhai Shijingshan Park. These field investigations entailed systematic observations of extant color schemes, their interactions with the natural and built environment, and their consequential effects on the overall visitor experience. By synergizing these complementary methodologies, our research endeavors to cultivate a diverse and information-rich dataset, fostering a nuanced comprehension of the role and implications of color in the context of marine cities. Through the analysis of the survey results, it was found that there are many people flowing through Zhuhai Square, and they are divided into three types, one is local residents, one is foreign visitors, and another is residents of the province. The majority of the survey respondents were middle-aged and elderly people, followed by teenagers, with a diversified target of visitors.The visitor survey and analysis table is shown in Table 3.  
In this paper, the researchers focused on the color elements of the landscape in Zhuhai Plaza and conducted five evaluations: very satisfied, satisfied, ordinary, bad, and very bad. By utilizing post-evaluations, the researchers aimed to understand the satisfaction levels of tourists regarding the color of Zhuhai Plaza's landscape.
