Abstract

The aim of the present study was to investigate and compare the performance of various color matching procedures inclusive of color matching based on Allens rough match and an iterative procedure using the CIELAB color difference formula, spectrophotometric procedures such as McGinnis least square method, iterative method, weighted iterative method and spectrophotometric color matching based on fundamental color stimulus. To this end, 165 samples were dyed. Initially, the comparisons were made theoretically on the basis of color differences and indices of metamerism. Additionally, such comparison was extended practically by dyeing 24 real dyed samples. Practical results were in good agreement with the theoretical results, showing a relatively better performance of the spectrophotometic color matching procedure based on the fundamental color stimulus.
