正常的颜色感知是复杂的。但在初始阶段，它相对简单，因为在光水平上，它只依赖于三种光感受器类型的激活：长（L‐）、中（M‐）和短（S‐）波长敏感锥体。了解每种类型对不同波长的反应——三锥光谱灵敏度——可以用来模拟人类的色彩视觉，并在实际应用中指定颜色和预测颜色匹配。CIE已经批准了Stockman和Sharpe的锥光谱灵敏度估计（Stockman和Sharpe， 2000, Vision Res）及其相关的发光效率测量作为色觉的“生理相关”标准（CIE, 2006; 2015）。对于具有正常视锥光色素和平均眼透明度的平均“标准”观察者，LMS视锥光谱灵敏度被指定为5 - nm和1 - nm步长，这两者在人群中都是不同的。在这里，我们提供了三个锥体光谱灵敏度以及黄斑和晶状体色素密度光谱的公式，它们都是波长从360到850 nm的连续函数。这些函数再现了2度和10度的表列离散CIE LMS锥光谱灵敏度，在线性和对数单位上误差很小。此外，这些公式可以很容易地计算非标准锥体光谱灵敏度（和其他颜色匹配函数），包括黄斑、晶体和光色素光学密度的个体差异，以及适用于正常或红绿色觉缺陷观察者的光谱移位混合或多态L -和M -锥体光色素。
Normal color perception is complicated. But at its initial stage it is relatively simple, since at photopic levels it depends on the activations of just three photoreceptor types: the long‐ (L‐), middle‐ (M‐) and short‐ (S‐) wavelength‐sensitive cones. Knowledge of how each type responds to different wavelengths—the three cone spectral sensitivities—can be used to model human color vision and in practical applications to specify color and predict color matches. The CIE has sanctioned the cone spectral sensitivity estimates of Stockman and Sharpe (Stockman and Sharpe, 2000, Vision Res) and their associated measures of luminous efficiency as “physiologically‐relevant” standards for color vision (CIE, 2006; 2015). These LMS cone spectral sensitivities are specified at 5‐ and 1‐nm steps for mean “standard” observers with normal cone photopigments and average ocular transparencies, both of which can vary in the population. Here, we provide formulae for the three cone spectral sensitivities as well as for macular and lens pigment density spectra, all as continuous functions of wavelength from 360 to 850 nm. These functions reproduce the tabulated discrete CIE LMS cone spectral sensitivities for 2‐deg and 10‐deg with little error in both linear and logarithmic units. Furthermore, these formulae allow the easy computation of non‐standard cone spectral sensitivities (and other color matching functions) with individual differences in macular, lens and photopigment optical densities, and with spectrally shifted hybrid or polymorphic L‐ and M‐cone photopigments appropriate for either normal or red‐green color vision deficient observers.
