In this paper, we propose practical algorithms for the pigment color separation and synthesis of the human skin color to be used on mobile phone with camera. These algorithms overcome the limitation of the conventional algorithm such as using polarizing filters. The pigment colors are separated based on the proposed empirical pigment vector. The empirical vectors are extracted from skin color database. We evaluated the proposed algorithms for 45 images (5 persons, 3 cameras, 3 illuminants). The evaluated results showed that the proposed algorithms performed well on most of skin images.
