Topology-based Color Matching Model Design For Administrative Districts

Color collocation harmony is an important criterion to measure color scheme and color image.As a visual information expression product,color is one of the important map language,which can not be ignored in map design.The district map is one of the maps.The color matching style of these faceted elements often determines the visual feeling of a map.So the color matching of administrative division map needs extra attention.But at present,most of the color matching only consider the coordination of tone,not the map area,the total side length and color combination,a certain degree of determination Quantitative color allocation leads to some defects in color collocation of administrative maps.Therefore,in order to give users a better perception and experience,this article will do the following research:(1)Summarizing the defects existing in color matching of administrative regions at present,emphasizing the importance of the ratio of side length to area of adjacent areas in color matching design of administrative regions,combining the existing theory of color harmony the theory of color division with the degree of visual harmony of human beings,and exploring a new color matching method —— color topology color matching,which can be used to solve the problem of quantitative color matching in administrative color matching.(2)In order to meet the needs of the public for the harmony of map vision,by combining the analysis results of color stimulus samples with the H model and color topology rules,the map color matching model is established based on the color topology rules by quantitatively combining the color area ratio,the co-edge length of adjacent areas,the area ratio and the visual center(3)The color topology model is used to color administrative maps in multi-level and multi-color numbers.The reform and innovation of color collocation of administrative maps are realized.(4)Data entry before and after improvement of color matching model by automatic analysis software developed by Visual Studio software On the other hand,it also verifies the artistic sense of the color matching model,summarizes the rules ofcolor matching design of the excellent administrative region,lays the foundation for future research,and can reflect on the shortcomings of the design.
