On neutral trials, six letters were selected randomly to appear in the same color (we refer to this as the majority color). The other six letters each appeared in a different color, which was selected randomly without replacement. The spatial location of all colored letters was randomly selected so that stimuli would not be grouped by color. On neutral trials for both Experiments 2a and 2b,the target letter could appear randomly either in the majority color or as any of the other colors. Thus, a color cue was not informative on neutral trials
