Yellowness of paper or board
The influence of factors such as temperature, chemical reactions, and radiation can turn white or colorless materials such as art equipment, paper, and paints yellow.
The yellowness number indicates the change in the yellow value of a sample due to one or more of the abovementioned reasons. This method is used to describe the yellowness of near-white or near-colorless materials.
The yellowness value of a sample is calculated based on the standard color values X, Y, and Z. A color-measuring device is used to measure these standard values.
