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