In the previous paper (Part 1), the effect of hue on impulsivity and arousal were studied. From those results, yellow, red and orange were selected for further investigation since participants’ performance was consistent with a low arousal state (high error rate and long response time) on the yellow background and high arousal state (low error rate and short response time) on the red background whereas orange was the color that tended to result in high impulsivity. This paper will mainly investigate the fundamental theory of how chroma influences people’s impulsivity and arousal states. The same as in the previous paper, the two main factors used to measure impulsivity and arousal in this paper are also response time and error rate for each colored background. In the psychophysical experiment, participants were looking at backgrounds in three hues (red, yellow and orange) with different chroma levels on screen to complete a range of psychometric tests. During the experiment, participants gave their response to the psychometric test as quickly and accurately as possible. From the results it can be seen that chroma has a significant influence on participants’ response time and error rate, and influences impulsivity and arousal. Gender difference will also been discussed in this paper.
