Abstract
Seventeen direct dyes from a commercial source were used for dyeing cotton fabrics. The lightfastness of these dyed samples was measured by two methods namely by the blue scale method and by colour difference analysis. From the results obtained, it was noted that the colour difference method is more definitive and truly measures the degree of light fading.
