Under the same light source Next, when comparing two color samples, one observer thinks it is reddish while the other observer thinks it is greenish. This phenomenon is called "observer color change"

When a color is in the color matching process, the selected dye and the dye used in the standard sample may have a color change, so the chance of encountering the color change during color matching is high.
