¹l value: Indicates the lightness of an image, the higher the value, the greater the brightness; a value: Distinguishes the redness of the tongue body and the thickness of the tongue coating; b value: Distinguishes the white/yellow of the tongue coating, positively correlated, a white coating has a lower overall b value, while a yellow coating has a higher overall b value.
