在本文中描述了一种方法，发现经验，用于计算近似数量的“最小可感知的差异”之间的任何两种颜色的相同亮度的规格是可用的。这种方法以简单的形式作为经验关系式提出，它与下列类型的现有灵敏度数据基本一致：（1）纯光谱中可察觉的最小波长差是波长的函数（Steindler，Jones）;（2）在恒定纯度下可感知的最小主波长差，作为纯度的函数（沃森，廷德尔）;（3）在恒定主波长处可感知的作为纯度的函数的最小纯度差（Donath）;（4）在接近零纯度处可感知的作为主波长的函数的最小纯度差（Priest，Brickwedde），以及（5）可感知的作为色温的函数的最小色温差（Priest）。包括混合图，显示由其三线坐标和由其刺激的主波长和纯度指定的颜色。从这张图中，可以读出任何两种亮度相同的颜色之间的“最小可察觉差异”的数量，其确定性程度由这里给出的比较所指示。（“感觉”，“兴奋”）曲线，这表明了视觉的三个组成部分的理论（杨-亥姆霍兹）;但它已被重新表示的曲线，这表明一个服从色彩理论（赫林）。由于这种重新表述几乎和原来的表述一样方便，因此可以得出结论，经验关系所证明的这种成功不能作为任何一种理论形式的论据，而只能作为一种比这两种形式都复杂的理论，如G.

There is described in the present paper a method, discovered empirically, for computing the approximate number of “least perceptible differences” between any two colors of the same brightness whose specifications are available. This method has been stated in simple form as an empirical relation; it is shown to be in substantial agreement with extant sensibility data of the following types: (1) the least wave-length difference perceptible in the pure spectrum as a function of wave length (Steindler, Jones); (2) the least dominant-wave-length difference perceptible at constant purity as a function of purity (Watson, Tyndall); (3) the least purity difference perceptible at constant dominant wave length as a function of purity (Donath); (4) the least purity difference perceptible near zero purity as a function of dominant wave length (Priest, Brickwedde), and (5) the least color-temperature difference perceptible as a function of color temperature (Priest). A mixture diagram is included showing colors specified by their trilinear coordinates and by the dominant wave length and purity of their stimuli. From this diagram the number of “least perceptible differences” separating any two colors of the same brightness may be read with a degree of certainty indicated by the comparisons here presented.The empirical relation was originally expressed in terms of distribution (“sensation,” “excitation”) curves which suggest a three-components theory of vision (Young-Helmholtz); but it has been re-expressed in terms of curves which suggest an opponent-colors theory (Hering). Since this re-expression is nearly as convenient as the original expression, it is concluded that such success as has been demonstrated for the empirical relation can not be used as an argument for either form of theory; rather is a theory suggested which is more complex than either, such as that of G. E. Muller.
