Realism scores comparing the empirical dataset approach with the two existing models of spectral reflectance.

For all metrics lower numbers indicate greater realism. The shaded columns contain the most important realism metrics. The left concerns individual reflectance functions, and the right the distribution of colours arising. The ‘+5’ note for Ostwald-shading reminds of the number of parameters tuned to minimize the ID scores.对于所有指标而言，数值越低则真实感越强。带底纹的列包含最为关键的真实感相关指标。左侧列对应单个反射函数（reflectance functions），右侧列对应由此生成的色彩分布。针对奥斯特瓦尔德明暗法（Ostwald-shading）的“+5”标注，提示了为最小化ID分数所调整的参数总数。
