    Abstract: Methods and apparatus for calibrating a color measuring instrument with a color standard and verifying the color standard and calibration are provided. One method includes providing a color standard having a surface with at least two different colors (preferably arranged for a simultaneous color measurement), calibrating the instrument, and verifying that said color standard is an authorized color standard of a predetermined specification and that the calibration of the color measuring instrument has achieved predetermined specified results. Some of the provided methods and apparatus use a photosensitive portion that changes color when exposed to light. Various color standards for use with this invention are provided.

    Abstract: A method and apparatus for determining the condition of a test subject based on color uses a color measuring instrument to detect change in a color factor indicative of a condition such as a disease, spoilage, ageing, etc. A medical condition such as hyperbilirubinemia that affects skin color can be detected. One measures color factors such as Hunter b and L in the subjects' skin color. For predetermined ranges of one color factor, in particular L, changes in the other color factor, e.g. Hunter b, above predetermined levels are indicative of the medical condition. In many cases, a single measurement of the color factors can be utilized as a warning of the likelyhood of the medical or contaminated condition, if the ordinary range of the color factor is known for healthy individuals with skin coloration like that of the test subject. Even if there has been no baseline measurement and the test subject's color is such that a single reading of one or two color factors will not warn of the possible presence of the medical condition or contamination, sequential readings can indicate the presence or absence of the condition based upon changes in the measured color factor, or lack of changes. The color measuring techniques apply to a wide range of biological test subjects (e.g. hair, teeth, tissue, excretions, foods, soil, animals, plants).

    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.

    Abstract: A method for the selection of proper colors for individual wearers depending upon the underlying color of the skin of the wearer and the intensity therefor. The method includes the steps of providing a group of classifications of color temperature, preferably four in number, and using a spectrophotometer, or a draping technique of material to determine the color temperatures of the skin of the user, and a determination of the classification in which those color temperatures fall is made. A predetermined group of colors are classified within each category, so that upon determination of the proper classification for an individual user, reference may be made to the proper predetermined group of colors as a guide for appropriate apparel, cosmetic make up, or hair tint selection.
