In the past, engineers of quality assurance department matched color by eyesight or colorimeter to identify the change of hue. However, the method does not offer the best accuracy, nor does it indicate color strength. In this study, Everlight Chemical Industrial Corporation attempted to find a better measurement of the color strength and used the statistical analysis to get the estimated equation.

The findings in this article aim to demonstrate that the strength method of color measurement in anodizing dyes is more reliable than the color lightness method. In addition, the strength method can effectively reduce the time spent on training personnel to match color.
