Research on Green glass of Cantonese colored windows based on color model

Based on the color model, this paper investigates the green glass in Cantonese colored windows, aiming to establish the standard value of the green color of Cantonese colored windows, and to provide relevant data and suggestions to protect the design concept of Cantonese architectural decoration and regulate the use of color in colored windows. By collecting samples, with the help of image processing and color analysis software, the green glass was positioned and analyzed in both RGB and LAB color models. It is found that in the RGB color model, the threshold intervals of green glass are mainly concentrated in the Forest Green and Green regions; in the LAB color model, the threshold intervals of the two-color channels of green glass are mainly distributed in the range of medium and low saturation. This study provides digitalized standard values and reference data for the green of the Cantonese colored windows, which helps to maintain the design style of traditional architecture and promote the development and application of colored windows.
