3名受试者单眼中央凹观察直径为0.6 °的单色测试野，该测试野被内径为0.6 °、外径为4.5 °的白色环包围。中心测试场的波长以10 nm的步长从440 nm变化到640 nm，并且其亮度设定为100 Td。中心和环绕每4秒一起闪烁2秒。受试者调整周围环境的亮度，使中心区域被感知为具有等量的白度和黑度。该平衡点所需的环绕的亮度随着测试场的波长以非常类似于在类似条件下获得的异色亮度匹配函数的方式变化。对照实验排除了受试者在中心和周围视野之间进行亮度匹配的可能性。提供的其他证据表明，假定的白-黑通道的光谱响应度最好由基于相等亮度的明视光谱灵敏度曲线表示。
Three subjects viewed, foveally and monocularly, a monochromatic test field of 0.6-deg diameter that was surrounded by a white annulus of 0.6-deg inner diameter and 4.5-deg outer diameter. The wavelength of the central test field was varied in steps of 10 nm from 440 to 640 nm, and its luminance was set to 100 Td. Center and surround were flashed together for 2 sec every 4 sec. The subjects adjusted the luminance of the surround so that the central field was perceived as having equal amounts of whiteness and blackness. The luminance of the surround required for this balance point varied with the wavelength of the test field in a manner that closely resembled a heterochromatic brightness matching function obtained under similar conditions. Control experiments ruled out the possibility that the subjects were making brightness matches between center and surround fields. Additional evidence was provided suggesting that the spectral responsivity of the putative white-black channel is best represented by a photopic spectral sensitivity curve based on equal brightness.
