Colour matching and colour constancy were studied in seven patients and 46 control subjects. Subjects were required to match Munsell Colour Chips presented under either identical or different illumination. Three of the patients had deficits in colour constancy, i.e. failure to compensate for the change in the wavelength composition of the illumination. Two of the patients with defective constancy had suffered bilateral cortical damage to the posterior lingual and fusiform gyri, and one patient had a lesion restricted to the same regions of the right hemisphere. Our observations indicate that these cortical areas, which include part of putative human area V4, play an important role in colour constancy.
对7名患者和46名对照者进行了颜色匹配和颜色恒常性研究。受试者被要求匹配在相同或不同光照条件下呈现的孟塞尔色卡。其中3名患者存在颜色恒常性缺陷，即无法补偿光照波长组成的变化。两名颜色恒常性有缺陷的患者双侧后舌回和梭状回皮质受损，一名患者的病变局限于右半球的相同区域。我们的观察结果表明，这些皮质区域，包括假定的人类V4区的一部分，在颜色恒常性中起重要作用。
