Although the two colors "standard sample" and "comparison sample" can match the color of a specific light source, but become inconsistent under another light source, this is called color change, and these two colors are called "color change pair". The reasons and explanations are:
The physical explanation is that there is a pair of colors whose spectrums are different but the same under a certain light source. This pair of colors is called "metamerism", and of course it will be different immediately after changing other light sources. A further explanation, under a specific light source (we call it the first light source), the standard sample and the comparison sample are adjusted to the same triple value, so the two colors appear to be the same, but under another light source (we call it the second light source) Light source) The standard sample and the comparison sample have three laser values not necessarily the same. The reason for this is that the second light source, the intensity of each wavelength from the wavelength spectrum 400μm to 750μm is inconsistent with the original first light source, so it is reflected on the color sample. The intensity of the light will be different, the intensity will be different, the three-excited value will be different, and the three-excited value will be different, the color feeling formed by the brain will not feel the same as the first light source.
