摘要：
In order to improve the coordination and unification between the tunnel portal and the natural environment， the color theory and image processing technology are applied to study the color coordination of highway tunnel wall portal with the environment in China. In this paper，by conducting a survey questionnaire and introducing the hue coordination theory，the design criteria for the color coordination of tunnel portals are constructed，that is，the hue conforms to the harmonic coordination type，and the saturation and lightness are both weak contrast types. Based on this criteria，a quantitative design method for tunnel wall portal color is proposed. The cluster analysis is used to extract the color attributes of the tunnel entrance environment image and convert them into the HSV（hue，saturation，value）color space. The hue harmonic type is analyzed，the saturation and lightness are calculated，and the value range of the three attributes of the portal color is determined. A case study of an existing tunnel is conducted using the color design method， and the coordination evaluation results are consistent with the subjective questionnaire results，which verifies the feasibility and effectiveness of the method and provides a scientific basis for the design of new tunnel portals. © 2023 Science Press.
