Abstract
Abstract The invention relates to a method and Apparatus for determining the color of a foundation makeup comprising a device for measuring the color of the skin on an arm of a person computing and determining the skin color measured and comparing same with a data base containing a palette of reference foundation colors substantially covering a representative sample of a population of given individuals, the data base containing at least the color of the skin for each individual and a reference foundation color associated with one or more of the skin colors in the data base; and determining from the data base the foundation color associated with the skin color to reproduce the skin color in the data base corresponding to the measured skin color of a person.
