The visibility threshold of a color gradient across the screen is determined for the specific application of mobile displays. The color gradient was implemented as a change in saturation or in hue from the center of the screen towards the edges in horizontal direction. Its visibility threshold is determined in a double-stimulus subjective test. To investigate the influence of the way stimuli are presented in this type of tests, each pair of stimuli is shown twice to the subjects: once with the two stimuli of the pair simultaneously, and once with the two stimuli of the pair time-sequentially. The results exhibit a remarkable difference in the effect of the way stimuli are presented between the visibility in a saturation gradient and in a hue gradient.
