The compatibility value of the dye is assessed by determining its dyeing behaviour in combination with each of a series of reference dyes in the relevant scale. Compatibility is assessed against one of two defined five-step scales: a yellow scale and a blue scale. The assessments are made using the scale showing the greatest difference in hue from that of the dye under test.
