The colorimeter is mainly used to detect the color of products. In tobacco industry, the quality of tobacco leaves is often judged by their luster and color, and the grade of tobacco leaves is determined. Tobacco grading is also an important link in industrial and commercial handover. The current national standard of flue-cured tobacco in China stipulates that flue-cured tobacco should be graded first and then graded. Tobacco color refers to the related color, color saturation and color value of the same type of tobacco after modulation, so color recognition is directly related to the rationality of classification.
