Abstract:
A method for selecting paints is disclosed. This method includes the steps of selecting true paint colors, displaying device-dependent colors corresponding to the true paint colors in a simulated full size room and interacting with the buyers to change the displayed colors and select the desired colors. The method also includes the step of dispensing paints corresponding to the selected colors. The displayed colors are generated by multiple color and/or white LEDs to provide a wider gamut of displayable colors and more color saturation and chromatic. A full-size apparatus for displaying paint colors using device-dependent colors is also disclosed.
Abstract:
In order to obtain calorimetric data close to the color appearance under an actual viewing condition, a plurality of conversion data for converting calorimetric data measured under the first geometric condition of colorimetry into that measured under the second geometric condition of colorimetry are held, and the information of a viewing illuminant and calorimetric data measured under the first geometric condition of colorimetry are obtained. Conversion data which corresponds to the information of the viewing illuminant is interpolated from the plurality of conversion data which are held. The calorimetric data measured under the first geometric condition of colorimetry is converted into that measured under the second geometric condition of colorimetry using the interpolated conversion data.

Abstract:
The present method invention provides a portable method useful for identifying the effect pigments used in developing a color matched formula for a vehicle repair paint. The method comprises observation of effect pigment properties of the coating of a vehicle to be matched, in a field location with a portable magnification apparatus, and comparison of the effect pigment properties with reference sample(s) properties of available effect pigments, thus enabling precise selection of effect pigment(s). The method may also utilize features derived from images of physical reference samples of available effect pigments, for comparison purposes. Further, the method may, in a field or centralized laboratory location, utilize a comparison of the effect pigment properties of images of the vehicle coating to be matched, or features derived from images thereof, with images of reference samples of available effect pigments, or features derived from images thereof, thus enabling precise selection the effect pigment or pigments to use in the development of said color matched formula.
