以长春市三大历史文化街区为研究对象，对片区内具有意象特征的建筑进行现状及测色调研，总结其现状色彩布局 特征。现状表明，历史文化建筑与居住建筑的色彩较为统一，商业建筑、休闲娱乐建筑与文化建筑用色较为丰富。基于“区 域统一”和“单体特色”两个规划要点，提出色彩图谱与规划建议，既能表现区域文化特征，延续建筑文脉，又能在后期的 城市品牌建设中形成线上线下统一的城市形象感知模式。

Taking Changchun's three major historical and cultural districts as the research subjects, this study conducted a survey on the current status and color measurement of buildings with iconic characteristics within these areas. It summarized the existing color layout patterns, revealing that historical and cultural buildings exhibit relatively uniform color schemes compared to residential structures, while commercial buildings, leisure and entertainment facilities, and cultural venues feature more diverse color palettes. Guided by the planning principles of “regional unity” and “individual character,” this study proposes a color palette and planning recommendations. These solutions effectively express regional cultural identity and preserve architectural heritage while establishing a unified online and offline urban image perception model for future city branding initiatives.
