## 3 Methodology
### Survey Analysis
The analysis of user feedback and satisfaction with the color of the plaza's landscape provides valuable insights for planning and designing landscapes, facilities, and buildings in the area. By setting up these five evaluation categories, the researchers were able to capture a wide range of responses and opinions from tourists visiting Zhuhai Plaza. The inclusion of \"very satisfied\" and \"very bad\" categories allows for extreme responses, highlighting the potential for both positive and negative experiences with the color elements of the landscape. This comprehensive evaluation approach enables a more nuanced understanding of user preferences and satisfaction levels. Moreover, the analysis of user feedback and satisfaction levels contributes to an understanding of the public opinion. By summarizing the color preferences and satisfaction levels of visitors to Zhuhai Plaza, the researchers can gain insights into the preferences of the local community and tourists alike. This information is crucial for future planning and design endeavors in the area, as it allows decision-makers to align their color choices with the desires and expectations of the public. Figure 3 provides a visual representation of the satisfaction levels of tourists regarding various categories of the square space color in Zhuhai Plaza. The horizontal axis depicts specific categories of color design, including the overall color design of the square, ground pavement color design, building facade color design, landscape color design, and green plants and flower color matching. The numerical axis represents the satisfaction levels, with a range from \(-2\) to \(2\), where negative values indicate dissatisfaction and positive values indicate satisfaction. The numerical axis represents the satisfaction of the tourists; \(-2\) to \(-1.1\) means very bad, \(-1\)-\(0.1\) means bad, \(0\) means average, \(0.1\)-\(1\) means satisfactory, and \(1.1\)-\(2\) meets the standard very satisfactory. The results from Figure 3 highlight the overall satisfaction levels of tourists with the color design of Zhuhai Plaza. The highest satisfaction levels were observed in the \begin{table}
\begin{tabular}{c c c} \hline \hline  & **Proportion of Floor Area** & **Proportion** \\ \hline \multirow{3}{*}{Place of ownership} & Native Person & 76\% \\  & Outsider & 23\% \\  & Foreigners & 1\% \\  & Below 18 & 4\% \\  & 18–35 & 19\% \\ \multirow{2}{*}{Age} & 36–50 & 36\% \\  & 50–60 & 15\% \\ \multirow{2}{*}{} & Above 60 & 26\% \\ \hline \hline \end{tabular}
\end{table} 
Table 3: Investigation and analysis of tourists. Figure 3: Landscape color evaluation form of the plaza. overall color design of the square (category 'RQ1'), the landscape color design (category 'RQ3'), and the color design of the building facades (category 'RQ14'). These findings indicate that tourists found these aspects of the color design to be particularly appealing and visually pleasing. Conversely, when analyzing the survey results, there was a contrasting trend in categories that garnered the lowest satisfaction levels, specifically concerning the cultural infrastructure color scheme design (category \"RQ5\") and the ladder color design (category \"RQ9\"). The data highlight that tourists expressed notably lower levels of satisfaction when evaluating the color choices and design implementation in these specific areas of Zhuhai Plaza. To better understand these results and derive meaningful insights, it is essential to delve into potential explanations for the lower ratings. In the case of the cultural infrastructure color scheme design (\"RQ5\"), the diminished satisfaction levels could be attributed to a disconnect between the color choices made for these elements and their intended cultural significance or historical context. It is plausible that tourists expected a more harmonious integration of colors that resonate with the cultural heritage of the area, and the discrepancies in this regard might have led to the lower satisfaction scores.
