Grey Scales facilitate the assessment of change in colour or staining, on a scale of 1-5 (with four half steps), with 5 being good and 1 being poor.
The ‘colour change’ scale is used to evaluate colour shade change in colour fastness tests, eg washing, water, perspiration and light (fastness assessment).
The ‘staining’ scale is used to evaluate the degree of staining on undyed adjacent fabrics during colour fastness testing (staining assessment).
