Stimulus Array (color online) – An example of the stimulus array with the elements alternating between the two colors. In one task (yoked hue pairs) the hue angle between the two components remained constant and the pair were varied together to make the setting. In the second task (fixed single component) the color corresponding to the corner elements remained fixed while observers varied the hue of the second component.
