Independent researchers have proved mathematically that, given a set of color-matching functions, there exists a unique set of three monochromatic spectral lights that optimizes luminous efficiency and color gamut. These lights are called prime colors. We present a method for transforming reflectance spectra into Munsell color space by using hypothetical absorbance curves based on Gaussian approximations of the prime colors and a simplified version of opponent process theory. The derived color appearance system is represented as a 3D color system that is qualitatively similar to a conceptual representation of the Munsell color system. We illustrate the application of the model and compare it with existing models by using reflectance spectra obtained from 1,269 Munsell color samples.
独立研究人员已通过数学方法证明，给定一组颜色匹配函数，存在一组独特的三原色光谱光，可优化发光效率和色域。这些光被称为原色。我们提出了一种方法，通过使用基于原色高斯近似的假设吸收曲线和对立过程理论的简化版本，将反射光谱转换为孟塞尔颜色空间。导出的颜色外观系统表示为一个三维颜色系统，在定性上类似于孟塞尔颜色系统的概念表示。我们通过使用从1269个孟塞尔颜色样本获得的反射光谱来说明该模型的应用，并将其与现有模型进行比较。
