Color is easily observed by product users and is mainly used for production control. exist In some cases, color can be used as an indicator of the degree of refinement of the raw material. If the color range of a particular product is known, then when If the color is out of the determined range, the sample may be contaminated. However, color is not always a reliable indicator of product quality, especially in product specifications to be screened for use.
