A gray scale is used for visually evaluating the colorfastness of textiles. There are two types of gray scales. one for assessing color change and another for assessing staining. The Gray Scale is an essential tool for textile product developers and manufacturers, as it helps determine the suitability of fabrics for specific applications based on their colorfastness. The ISO Gray Scale for Color Change consists of nine pairs of colored chips, 5, 4-5, 4, 3-4, 3, 2-3, 2, 1- 2, and 1, which illustrate how much a fabric’s color changes due to external factors like washing and exposure to light as described in ISO 105-A02. The result of a colorfastness test is evaluated by visually comparing the difference in color between the original (un-tested) and the tested specimens with the differences represented by the gray scale number grading. The color change grade is equal to that of the gray scale pair that is judged to have the same color difference. Results are reported as a gray scale for color change grade of 5 to I, with 5 representing no color change and 1 representing the most color change. This tool helps manufacturers determine whether a fabric will maintain its color over time under various conditions.

A gray scale is used for visually evaluating changes in color of textiles resulting from colorfastness tests. There are two types of gray scale. One for assessing color change and another for assessing staining. The Gray Scale is essential for textile product developers and manufacturers, as it helps determine the suitability of fabrics for specific applications based on their colorfastness. The ISO Gray Scale for Staining is tool used to measure any unintended staining and color transfer on a 1 to 5 scale according to ISO 105-A03. This scale helps determine whether a fabric will bleed or lose its color over time and under various conditions. The grey scale consists of nine pairs of non-glossy grey and white colored chips showing the grade of staining. These give a corresponding fastness rating of 5, 4-5, 4, 3-4, 3, 2-3, 2, 1-2, 1. ISO Gray scales for staining are used to assess the amount of staining occurring on adjacent undyed fabrics during fastness tests. The transference of color from the test specimen to an adjacent specimen is evaluated using five standard pairs of color chips. One half of each standard is white, and the second half ranges from white to gray. The bottom half of each color chip pair shows the untested starting color. The top half shows the color of the adjacent fabric after testing. A value of 5 corresponds to virtually no staining, whereas 1 indicates poor color-fastness.

Standard Depth Matt
Standard Depth Scales. As the fastness of dyeing depends on the depth of colour it is necessary to specify standard depths when making comparisons. Dye manufacturers pattern cards refer to these depths in fastness ratings for their products. SDC standard depths are illustrated in a range of 6 steps each from 2/1 to 1/25 depth over a range of 18 hues plus 2 navies and 2 blacks.
