Abstract :
We made color change experiments by utilizing a dichromatic reflection model. Also, we compare our method with a method based on HSI (hue, saturation, and intensity). The experimental results show that the method based on the dichromatic method is more effective. However, it is difficult for the method based on HSI to deal with the saturation contrast. In addition, through experimental research on how to maintain uniformity of subjective color difference between the object and background when changing color, we obtain an algorithm which uses the reference point to determine the amplitude value of the new color vector. Our color change method is easily realized
