Abstract: Skin coloration categories are identified based upon opponent color underton es of the skin. For example, using a color measuring device (10), Hunter b value is developed from measures of blue, yellow and l ightness. That value alone then determines which of seve ral categories of skin coloration a subject's skin exhibits. Category selection is made by comparison of measured Hunter b with ranges o f Hunter b values of skin color categories. Instrumentation includes the color measuring device (10), a central processing unit (15), memory (17), and an output device. The skin color Hunter b is calculated and compar ed to stored ranges to assign a category which is then d isplayed on the output device. Colors compatible with skin color categories are ident ified or formulated based upon broad color family design ation, yellow, brown, red, etc., and a comparison of measured and stored ranges of known or specifically developed color characteristics fo r the particular family.
