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: Methods and systems for measuring with a Color Measurement System of predetermined specification and evaluating the color of skin, teeth, hair and material substances with a Color Index. The principles of this invention also relate to techniques for using such a Color Measurement System with the Color Index in medical applications such as the detection of chromogenic disease including bilirubin infant jaundice, cosmetics applications and in the evaluation of the color of hair or teeth, and other applications. The Color Index is measured and calculated from the reflectance spectrum of any skin (or teeth, hair or material substance) by a two step process. The first step is the weighting of the visible spectra with a unique set of weighting factors which calculate a sample's reflectance spectrum's contribution to the appearance of four color components independent of the illuminating condition. The second step places the sample's reflectance spectrum's contribution to the appearance of the four color components in opponency to each other and calculates the Color Index providing attributes representative of correlates of lightness-darkness (L, also referred to as lightness), redness-greenness (M) and yellowness-blueness (N).

Abstract: Un método y aparato para determinar la condicion de un sujeto de prueba en base al color utilizando un instrumento de medicion de color, para detectar el cambio de un factor de color indicativo de una condicion tal como una enfermedad, daño, envejecimiento, etc.. Puede detectarse una condicion médica tal como la hiperbilirubinemia, que afecta el color de la piel. Uno valora los factores de color tal como Hunter b y L en el color de la piel de los sujetos. Para rangos predeterminados de un factor de color, en particular L, los cambios en el otro factor de color, por ejemplo Hunter b, arriba de los niveles predeterminados, son indicativos de la condicion médica. En muchos casos, una sola medicion de los factores de color, puede utilizarse como una advertencia de la probabilidad de la condicion médica o contaminada, si el rango ordinario de los factores de color se conoce para individuos saludables, con coloracion de la piel similar a aquellas del sujeto de prueba. Aun si no existe medicion de línea basal y el color del sujeto de prueba es tal, que una sola lectura de uno o dos factores de color no advierten de la posible presencia de la condicion médica o contaminacion, las lecturas secuenciales pueden indicar la presencia o ausencia de la condicion en base a los cambios en el factor de color medido, o carecer de cambios. Las técnicas de medicion de color se aplican a un amplio rango de sujetos de prueba biologica (por ejemplo cabello, dientes, tejido, excreciones, alimentos, suelo, animales, plantas).
