The research that has been done in this field has been limited to establishing and applying a method of predicting the colour sensitivity of a matching recipe. This research help us the selection of dyes in a mixture recipe for dyeing. However, in practice, the effectiveness of the recipe solution by the concentration sensitivity could be only marginal and other parameters might be more important to the recipe performance than an error in the dye concentration. Therefore it is important to consider colour sensitivity in its widest possible context. Dye sensitivity is collection of various functional parameters. If we want to measure reactive dye sensitivity, we must know the conditions, type of dyes added, nature of dyeing (PDC, PB, Exhaust), what auxiliaries are added, time, temperature, liquor ratio, fabric etc. so many factors affected on the dyes sensitivity.
