In every investigation, hair color must first be defined by the researchers. Subjective color assessment inhibits the reproducibility of experiments and the direct comparison of results. The aim of this study was to objectively measure human hair color and examine the variation found in a population with European ancestry, using the CIE L*a*b* color space. Observer\u2010perceived hair colors were compared with self\u2010reported hair colors and the color as measured by reflective spectrophotometry of 132 subjects of European ancestry. The presented data show that self\u2010reported hair colors and observer\u2010reported colors are similar; however, these categories are not necessarily the best way to categorize hair color for quantitative research. Using a two\u2010step cluster analysis, hair color can be divided into categories or clusters based on spectrophotometric measurements in the CIE L*a*b* color space and these clusters can be well discriminated from each other. This separation is primarily based on the b* (yellow) color component and the clusters show agreement to observer\u2010reported colors. This study illustrates the possibilities for and necessity of objectively defining the hair color phenotype for various downstream applications.
