For example, when it is irradiated with visible light of a wavelength corresponding to the fading of magenta, diarylethene fades the magenta, leaving behind the yellow and cyan colors. The same is true for the fading of yellow and cyan, and fading of each color can be achieved by irradiating it with light of the corresponding wavelength.
