Abstract:
1. A method of matching a skin color comprising the steps of providing a color measurement device adapted to measure a first spectral reflectance curve of an area of skin to be matched, providing a colorant database containing a plurality of colorant spectral reflectance curves each for a respective one of a plurality of colorants, measuring a first spectral reflectance curve for a selected area of skin, comparing said first spectral reflectance curve to said colorant spectral reflectance curves and determining a recommended blend of colorants chosen from the colorant database, said recommended blend having a calculated spectral reflectance curve substantially corresponding to the measured first spectral reflectance curve for the selected area of skin, and recording in a formulation database a recommended blend of colorants found to constitute a successful match, together with respective spectral reflectance curves and color values for the blend.
