>In this study, we assessed the performance of the HIrisPlex-S system, which predicts eye, hair, and skin color, on 412 individuals from the Spanish population
>Blue-green, blue-brown, brown-green, brown-blue-green, green, grey, hazel, and light eyes were grouped into the intermediate category. Analysis of the distribution of eye pigmentation showed a majority of individuals with brown eyes (68.78%), followed by intermediate (22.75%) and blue eyes (8.47%)
>Upon observing the distribution of hair color, a predominance of individuals fell into the brown hair category (64.47%), followed by black (25.53%), blond (9.74%), and red hair (0.26%)
>When examining the distribution of skin color in our population, we observed that the majority of individuals were classified as having pale (53.43%) and intermediate (39.71%) skin tones, while dark skin exhibited very low representation (6.86%). No representation was observed for the very pale and dark-black skin categories
