The McCollough effect (ME) is an example of a pattern-contingent colour aftereffect. This study describes some characteristics of another visual aftereffect linking pattern and colour here called a colour-contingent pattern aftereffect (CCPA). After inducing with, for example, a magenta and black radial pattern and a green and black pattern of concentric circles, presentation of a green homogeneous field evoked a faint image of a radial pattern superimposed on the field, whereas presentation of a magenta homogeneous field produced a faint image of concentric circles. The pattern was blurred and fleeting, occurring with the onset of the homogeneous field, but nevertheless was evoked reliably. Various properties of these colour-contingent pattern aftereffects are reported. Although the aftereffects have some of the characteristics of the ME, the CCPA is not as long lasting as the ME, and, unlike the usual ME, it is abolished if eye-movements are made during induction.
麦科洛效应（ME）是一种模式相关的颜色后效的例子。本研究描述了另一种将模式与颜色联系起来的视觉后效的一些特征，这里称之为颜色相关模式后效（CCPA）。例如，在用品红色和黑色的放射状图案以及绿色和黑色的同心圆图案进行诱导之后，呈现绿色均匀场会在该场中诱发叠加有放射状图案的模糊图像，而呈现品红色均匀场则会产生同心圆的模糊图像。该图案模糊且短暂，在均匀场出现时出现，但仍然能够可靠地诱发。报告了这些颜色相关模式后效的各种特性。尽管这些后效具有麦科洛效应的一些特征，但颜色相关模式后效不像麦科洛效应那样持久，而且与通常的麦科洛效应不同的是，如果在诱导过程中进行眼球运动，它就会消失。
