In the 1960s, Jean‐Philippe Lenclos introduced a structured methodology for determining the color palettes of urban environments. After half a century, this method is widely used all over the world. Since this process contains subjective and time‐consuming steps, we propose a quantitative improvement of Lenclos' methodology by introducing a fully digital procedure. This removes observer subjectivity and dependence on local illumination conditions. We applied the digital process to the four monumental buildings of Naghsh‐e Jahan Square in Isfahan, a masterpiece of world architecture. The resulting color palettes are more accurate than those obtained in earlier studies. We obtained more accurate color coordinates, characterized by a wider color gamut, and quantified color variations within buildings and between monuments as well.

量化伊斯法罕Naghsh-e Jahan Square的调色板

在1960年代，让·菲利普·伦克洛斯（Jean‐Philippe Lenclos）提出了一种用于确定城市环境调色板的结构化方法。半个世纪后，这种方法在世界范围内被广泛使用。由于此过程包含主观且耗时的步骤，因此我们建议通过引入完全数字化的程序来对Lenclos的方法进行定量改进。这消除了观察者的主观性和对局部照明条件的依赖。我们将数字过程应用于世界建筑的杰作伊斯法罕的Naghsh-e Jahan广场的四座纪念性建筑。所得的调色板比早期研究中获得的调色板更准确。我们获得了更准确的颜色坐标，其特征在于更宽的色域，以及建筑物内以及纪念碑之间的量化颜色变化。
