Colour Difference Of Illuminant Metamerism Available to Purchase

Fifty-five metameric sample pairs were prepared using computer-predicted recipes from six different colour centres using cotton knit fabric. The colour difference of each sample pairs was measured using a datacolour Elrepho 2000 under the reference illuminant D6s, and test illuminant A and TL84. The colour difference of a sample pair under a specific illuminant is formed from three different components i.e. lightness, chroma and a* b* difference. Metameric colour difference should be attributed to the CIELAB a* b* difference and to a less extend of chroma difference but not to the lightness L* difference under the test illuminants.
