Abstract: This paper proposes a color matching method of polychromatic contour lines based on Munsell Color Harmony Theory for improving the color harmony in thematic maps. The working framework includes 3 aspects: category harmonization, direction harmonization and chromatism harmonization. Firstly, a basic color for contour lines is predestined with the habitual color used to be employed, and its corresponding harmony color subdomain is worked up. Secondly, several algorithms of color harmony between contour lines and land-use parcels are used based on Munsell’s color harmony directions, and a few candidate colors of contour lines are figured out according to their background parcels. Finally, the priority matching levels for contour lines are conducted by the distribution variation analysis of parcels and contour lines, and the optimal polychromatic contour lines are balance taking account to human feeling on chromatic aberration. Both the primary comparison experiments and questionnaire survey indicate that the polychromatic contour lines calculated by harmony color matching method provide more flexible and delicate visual effect for the land-use thematic maps.
