Contrast detection thresholds for spatiotemporal colour modulation were determined at several retinal locations. Colour discrimination is studied for red-green modulation of a yellow field and for yellow-blue modulation of a white field. For constant target size colour vision deteriorates if the stimulus is moved away from the fovea, but if the shift is combined with a suitable enlargement of the target size colour discrimination at the periphery is comparable to that at the fovea. We did not find any retinal location along the horizontal meridian which was red-green or yellow-blue colour blind. Chromatic bars were detected in the nasal peripheral retina at eccentricities of up to at least 50 degrees, temporal colour contrast was perceptible at nasal eccentricities of up to at least 90 degrees.
在视网膜的多个位置确定了时空颜色调制的对比度检测阈值。研究了黄色场的红-绿调制和白色场的黄-蓝调制下的颜色辨别。对于恒定的目标大小，如果刺激物从中央凹移开，颜色视觉会变差，但如果这种移动与目标大小的适当增大相结合，周边的颜色辨别与中央凹处相当。我们没有在水平子午线上发现任何红绿色盲或黄蓝色盲的视网膜位置。在鼻侧周边视网膜中，至少在高达50度的偏心度处能检测到彩色条，在高达至少90度的鼻侧偏心度处能察觉到颞侧颜色对比度。
