Abstract:
A paint color matching and coordinating system comprises an interface for receiving an input reference color, a processor capable of reading a memory, a memory including (1) instructions readable by the processor and (2) a database of architectural paint colors spanning all or most of the known color space, and a display generator. In use, the interface of the system receives an input reference color from a user. The processor selects a “reference paint color” from the database, the reference paint color being visually closer, with respect to color space, to the input reference color than any other paint color in the database. According to the invention, color space is divided into a plurality of fixed, generally equally sized, non-overlapping, contiguous portions, each color space portion being defined as the space of all colors within a band of hues within color space. The processor selects five sets of paint colors—one set from each of the color space portions that include the five hues that comprise the “five-way harmony” of the reference paint color. The processor may also select a sixth set of paint colors from the color space portion that includes the hue of the reference paint color. Finally, the processor directs the display generator to create a display of color samples of the reference paint color and of the first through sixth sets of paint colors.
Abstract:
A system and method for calculating harmonizing colors based on a reference color. In a first embodiment, the invention includes (a) defining a reference color in a uniform color space, (b) converting the hue of the reference color from the uniform color space to an artists color wheel, (c) determining harmonizing colors for the reference color within the artists color wheel, (d) converting the hues of the harmonizing colors from the artists color wheel to the uniform color space, and (e) displaying the harmonizing color information. In a second embodiment, a brown region is defined for colors having red/orange/yellow hues and low chroma values. Additional harmonizing colors are determined when either the reference color or one of the harmonizing colors falls within the brown region.
Abstract:
A method for simulating the final finish of a multi-component finish material comprises submitting or receiving a request describing a desired single or multicolor surface appearance in a finish simulator to generate one or more simulated appearance samples, obtaining feedback on said simulated appearance sample and, if necessary, modifying said sample to simulate said desired surface appearance. The finish simulator comprises a library of finish templates that have been produced and software or processing means to apply rules to adjust the simulated finish for known changes in chemistry, composition, and application conditions. In addition, the appearance of an actual multicolor sample is reproduced by separating the sample into areas of different individual colors, identifying the individual color of each of said areas, translating said individual area colors into color values that correspond to those in a database of colors that have been produced, and searching the database for existing colors that are close matches for those in the sample. The final finish of the closely matching colors is preferably simulated and assessed electronically using a finish simulator. The method of the present invention reduces the total time necessary to generate a multi-component color finish to match a given sample and can eliminate the need for making trial finishes in assessing color finishes for matching.

Abstract:
A device for determining aesthetically harmonious color combinations includes a color selector wheel rotatably attached to a base having a plurality of distinct color selection groups disposed beyond and surrounding the periphery of the color selection wheel. Each color group section forms a window through which samples can be viewed. The color selector wheel has color selection indicia in the form of at least one symmetrical geometric symbol centered on the face of the color selector wheel. The indicia each have a primary vertex and a plurality of secondary vertices disposed adjacent to the periphery of the color selector wheel such that alignment of the primary vertex with a selected color selection group automatically aligns the secondary vertices with harmonious color combination selection groups and allows the user to develop progressive color coordinating combinations.
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 likelihood 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:
A method and apparatus for selecting wearables, such as cosmetics and clothing accessories, which match an object of interest, includes control logic for selecting an appropriate wearable based on a metric determined by light reflected from the object. Light is transmitted by an input device which also detects the reflected light. The input device is connected to the control logic which determines a metric and compares the metric to predetermined data corresponding to each of the available wearables. The selected wearable is indicated to a customer by an output device also connected to the control logic. The output device may include a light corresponding to each available wearable, or a mechanical machine which provides the selected wearable or a sample of the selected wearable to the customer. In one embodiment the apparatus is utilized to match the color of a cosmetic foundation make-up to the color of the customer's skin.
Abstract:
Skin coloration categories are identified based upon blue and yellow undertones of the skin using a color measuring device, developing the Hunter b value, utilizing that value alone to determine which of several categories of skin coloration a subject's skin exhibits. Category selection is made by comparison of measured Hunter b with ranges of Hunter b value of skin color categories. Instrumentation to effect the method includes the color measuring device, a central processing unit (CPU), memory storing the ranges of Hunter b, and an output device such as a printer, LCD, or CRT. The skin color Hunter b is calculated and compared to stored ranges to assign a category. The output device displays the category of skin color based upon the central processing unit's comparison. Colors compatible with skin color categories are identified or formulated based upon broad color family designation, yellow, brown, red, etc., and a comparison of measured and stored ranges of known or specially developed color characteristics for 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 thereof. 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.
