Saturation and brightness, to a large extent, determine the color to the user's experience, the higher the saturation, lightness, the stronger the visual impact; Saturation, brightness is lower when on the vision milder. As can be seen from the below three pictures: when the saturation is at its lowest, the achromatic proportion is much more significant than the chroma proportion, and the picture becomes a "grayscale" diagram, which can be regarded as a "colorless" diagram.
