Color Scale Grading techniques are widely used to assess product color by comparison with a representative series of fixed color standards. For many product types, a characteristic set of standards was agreed and adopted to aid color control and the communication of color specifications; the result is a selection of traditional color grading scales that have been adopted as industry standards and are still in common use today.
