双色性理论认为，视锥细胞产生明视或色觉，而视锥细胞产生暗视或无色夜视。这篇文章报道了实验结果，证明了杆与长波锥体相互作用产生颜色感觉的能力。测定了只激发棒的546 nm和450 nm的辐射，以及只激发长波锥体的656 nm的辐射。当视杆和长波视锥被选择性地以看到形态所需的最小辐射激发时，观察者报告说看到了各种各样的颜色感觉。这些观察者还报告说，当视杆和长波视锥被选择性激发时，在更大的辐射下有相同种类的颜色感觉。由棒和长波锥体激发产生的颜色感觉与用于激发棒的波长无关。在视锥阈值以上时，视杆细胞和长波视锥细胞产生的色觉与656 nm和495±5 nm光产生的色觉相同，只是亮度和锐度略有不同。因此，在所描述的条件下，视杆可以和视锥一样成为人类产色系统的一部分。所有上述结果都可以用兰德的视网膜颜色视觉理论来解释。
The duplicity theory states that cones produce photopic or color vision, whereas the rods produce scotopic or colorless night vision. This paper reports experimental findings which demonstrate the capacity of the rods to interact with the long-wave cones to produce color sensations. Radiances of 546 and 450 nm that excited only the rods, and radiances of 656 nm that excited only the long-wave cones were determined. When the rods and long-wave cones were selectively excited with the minimum radiance necessary to see form, the observers reported seeing a large variety of color sensations. These observers also reported the same variety of color sensations at greater radiances when the rods and long-wave cones were selectively excited. Color sensations produced by the excitation of rods and long-wave cones were independent of the wavelength used to excite the rods. Color sensations produced by rods and long-wave cones were identical, except for slight differences of brightness and sharpness, to the color sensations produced by 656 and 495±5 nm light when both were above cone threshold. Therefore, under the described conditions, the rods can be as much a part of the human color-producing system as the cones. All of the above results can be explained by Land’s retinex theory of color vision.
