WebThe effect of separation on perceived color difference is an important aspect of color-difference evaluation. When evaluating color differences, three types of separation can be considered: hair-line, gap and ‘no-separation’ (NS). A hair-line is the virtual line which appears between a pair of samples when they are placed side-by-side.
