颜色类别之间的界限是否与增强的歧视有关？在本实验中，色度阈值得到沿正交线的颜色空间的黄-蓝轴的区别。目标是准中央凹的，阈值是用空间双选项强制选择来测量的。在交错的实验运行中，我们还通过要求观察者将颜色分类为红色或绿色，获得了主观黄蓝线的经验估计。这两种类型的测量都是在稳定的背景下进行的，该背景与等能白色同质。在从不饱和的黄色到不饱和的蓝色的有限区域内，在红色和绿色色调之间的主观过渡附近发现了增强的辨别。这条最佳辨别线不与色彩空间的任何一个基本轴对齐：在MacLeod-Boynton色度图中，它以负斜率倾斜运行。
Are boundaries between color categories associated with enhanced discrimination? In the present experiments, chromatic thresholds were obtained for discriminations along lines orthogonal to the yellow-blue axis of color space. The targets were parafoveal and thresholds were measured with a spatial two-alternative forced choice. In interleaved experimental runs, we also obtained empirical estimates of the subjective yellow-blue line by asking observers to categorize colors as reddish or greenish. Both types of measurement were made in the presence of a steady background that was metameric to equal-energy white. In a limited region from desaturated yellow to desaturated blue, an enhanced discrimination is found near the subjective transition between reddish and greenish hues. This line of optimal discrimination is not aligned with either of the cardinal axes of color space: In a MacLeod-Boynton chromaticity diagram, it runs obliquely with negative slope.
