Color vision and spectral sensitivity vary among individuals with normal color vision; thus, for many applications, it is important to measure and correct for an observer's sensitivity. Full correction would require measuring color and luminance matches and is rarely implemented. However, luminance matches (equiluminance settings) are routinely measured and simple to conduct. We modeled how well an observer's color matches could be approximated by measuring only luminance sensitivity, since both depend on a common set of factors. We show that lens and macular pigment density and $L/M$L/M cone ratios alter equiluminance settings in different ways and can therefore be estimated from the settings. In turn, the density variations can account for a large proportion of the normal variation in color matching. Thus, luminance matches may provide a simple method to at least partially predict an observer's color matches without requiring more complex tasks or equipment.

根据亮度匹配预测颜色匹配。


色觉正常的个体的色觉和光谱敏感度有所不同；因此，对于许多应用来说，测量和校正观察者的灵敏度非常重要。完全校正需要测量颜色和亮度匹配，但很少实施。然而，亮度匹配（等亮度设置）是常规测量的并且易于进行。我们通过仅测量亮度灵敏度来模拟观察者的颜色匹配的近似程度，因为两者都取决于一组共同的因素。我们表明，晶状体和黄斑色素密度以及 $L/M$L/M 锥体比率以不同方式改变等亮度设置，因此可以根据设置进行估计。反过来，密度变化可以占颜色匹配正常变化的很大一部分。因此，亮度匹配可以提供一种简单的方法来至少部分地预测观察者的颜色匹配，而不需要更复杂的任务或设备。
