Protanopes and deuteranopes do not accept the classical dichromatic matches when field size extends to 8 degrees visual angle. Their unique matches of spectral yellow to a mixture of red and green are then mediated by the photoreceptors of small-field dichromacy interacting with a photoreceptor with the spectral sensitivity of rhodopsin. Our data suggest that large-field trichromacy is a general feature of protanopia and deuteranopia.
当视场大小扩展到8度视角时，红色盲者和绿色盲者不接受经典的二色性匹配。此时，他们将光谱黄色与红色和绿色混合物的独特匹配是由小视场二色性的光感受器与具有视紫红质光谱敏感性的光感受器相互作用介导的。我们的数据表明，大视场三色性是红色盲和绿色盲的一个普遍特征。
