Participants adjusted the saturation of one rectangular color stimulus so that it appeared to match the saturation of another rectangular color stimulus for stimulus pairs of different relative areas. In Experiment 1, in which stimuli of complementary colors were used, higher saturation stimuli were consistently chosen for large areas to match lower saturation stimuli in smaller areas. In Experiment 2, better saturation matches were obtained if participants fixated and the stimuli were presented for very brief durations. In Experiment 3, larger color contrast effects were obtained with hue pairs that were nearer to complementary than with hue pairs that were more nearly the same. These findings agree with the interpretation that biases in relative saturation selected to match stimuli of different relative size are largely the result of negative afterimages of the larger stimulus having greater impact on the apparent saturation of the smaller stimulus.
参与者调整一个矩形颜色刺激的饱和度，使其看起来与另一个矩形颜色刺激的饱和度相匹配，用于不同相对面积的刺激对。在实验1中，使用互补色刺激，对于大面积的刺激，始终选择较高饱和度的刺激来匹配小面积中较低饱和度的刺激。在实验2中，如果参与者注视且刺激呈现时间非常短暂，则能获得更好的饱和度匹配。在实验3中，与颜色对更为接近的色相比较，与互补色更接近的色相能产生更大的颜色对比效果。这些发现支持了这样一种解释，即选择匹配不同相对大小刺激的相对饱和度偏差，很大程度上是由于较大刺激的负后像对较小刺激的表观饱和度产生了更大影响。
