We tested the Maxwell-Cornsweet conjecture that differential spectral filtering of the two eyes can increase the dimensionality of a dichromat's color vision. Sex-linked dichromats wore filters that differentially passed long- and middle-wavelength regions of the spectrum to each eye. Monocularly, temporal modulation thresholds (1.5 Hz) for color mixtures from the Rayleigh region of the spectrum were accounted for by a single, univariant mechanism. Binocularly, univariance was rejected because, as in monocular viewing by trichromats, in no color direction could silent substitution of the color mixtures be obtained. Despite the filter-aided increase in dimension, estimated wavelength discrimination was quite poor in this spectral region, suggesting a limit to the effectiveness of this technique.
我们对麦克斯韦-科恩斯威特猜想进行了测试，即对双眼进行不同的光谱滤波可以增加二色视者的色觉维度。性连锁二色视者佩戴的滤光片会将光谱的长波和中波区域分别不同程度地透射到每只眼睛。单眼情况下，光谱瑞利区域颜色混合的时间调制阈值（1.5赫兹）可由单一的单变量机制解释。双眼情况下，单变量假设被否定，因为如同三色视者单眼观察时一样，在任何颜色方向上都无法实现颜色混合的无声替代。尽管滤波有助于增加维度，但在该光谱区域估计的波长辨别能力相当差，这表明该技术的有效性存在局限。
