Abstract

The color is a common phenomenon in our society and life, and the existence of colors leads to color difference. Almost all walks of life have studied color difference, such as textile, printing, ceramics, building, digital display, image processing and so on. But so far, the study directly of threshold color difference of human eyes is very few. If wanting to research the color difference, firstly to produce colors which resulting in the color difference are needed. Recent studies have found that the sensitivity of human eyes distinguishing colors is more sensitive when using self-luminous color than using reflective color. An apparatus which can generate kinds of colors is designed by adjusting the color-mix machine which is placed between a small integrating sphere and a big integrating sphere. This can provide a precondition for measuring threshold color difference.
