| At this stage,my country’s urbanization is facing rapid development,while the research on urban color is still in its infancy.The color and features of many cities are lagging behind the local socio-economic development.For example,cold cities focus on research on protection from the cold.Related colors The relative lack of practice has resulted in more color pollution in the blind expansion and construction,which makes it difficult to effectively display the regional culture and individual characteristics of the city.Therefore,color planning plays a role in shaping the city’s style and enhancing the image and popularity of the city.The role of the stronger.However,urban color contains a large number of complex and changeable elements.Among them,the public,as the most direct recipient and evaluator of color stimulus,often expresses color perception with vagueness and subjectivity,thus exploring quantitative color investigation and analysis methods.It is particularly important to give scientific data support for color optimization.Therefore,this article attempts to combine Chinese color system methods,street view image big data,and semantic analysis methods that use "language" as a means to conduct psychometric analysis to analyze the current color of the block in Central Avenue,which is mainly divided into the following parts:First,the relevant theories and research status are explained from three aspects of cold city color,color perception and semantic analysis.Secondly,it constructs a semantic analysis-based color research framework from four aspects: the feasibility and effectiveness of the evaluation premise,the analysis of the basic color status of the evaluation,the evaluation of the color environment perception of the evaluation process,and the color environment optimization of the evaluation application.Thirdly,based on the analysis of the color background of the central street block,the current color situation is analyzed,the street view map is used for image collection,and the color card is used for comparison,and the basic color information obtained is screened,classified,converted,stored and stored.Analyze to evaluate the overall color style and material,function,number of layers and other color elements of the block.Next,conduct a perceptual evaluation of the color environment of the Zhongyang Avenue block.Through screening,determining evaluation factors,evaluation scales and interviewees,a psychological quantitative evaluation questionnaire for 18 evaluation factors of 19 streets is obtained,and then basic result analysis and SD scores are performed.And factor analysis,to obtain the user’s visual,psychological and spatial perception results of the current color.Finally,based on the analysis and perception evaluation conclusions of the current block color,combined with color planning principles and methods,a block-level color optimization proposal is put forward,and it is positioned as a "integrated,coordinated,and colorful" historical and cultural block.At the same time,due to the current status of high brightness and low color The warm color tendency of the degree is more in line with the characteristics of the cold city,so the theme color continues to use the "beige,off-white" hue.Reflected on the level of color grouping,in view of the user’s recognition of the color perception of the grouping is acceptable but not satisfactory,and different groups have differences in material,function and number of layers.Therefore,it is proposed based on the characteristics of the color grouping itself.Different recommended chromatograms,and provide style guidance for streets and key buildings with lower scores.In addition,information control systems,administrative and legal means,and public participation mechanisms are used to ensure the implementation of color control.Based on the qualitative color practice,this research proposes a quantitative analysis method based on the Chinese color system and semantic analysis.It is helpful to raise the problem of the color tendency of the block from the objective investigation and analysis of the current situation and the psychological subjective evaluation of the interviewees.Yu proposed a scientific and effective color control system,which also provides reference for other similar types of city color optimization. |
