  • Patent number: 9249331
    Abstract: A colored coating composition comprising a white base paint and at least one colored pigment in a form that can be readily mixed with the white base paint, the white base paint comprising a film-forming polymer, a liquid carrier, one or more opacifying white pigments and one or more extenders, the colored coating composition having a light reflectance value Y less than 110, and greater than that defined by the equation Y=mC+K, where 25>C>1.0, C being the chroma of the colored coating composition, m and K being empirical coefficients selected according to the type and number of the type of the at least one colored pigment, and dependant on the hue angle of the coating composition.

  • Patent number: 8885934
    Abstract: Embodiments of the invention relate to the determination of the color of a color sample from an image of the color sample. In one embodiment a color sample capture card is provided having printed thereon color samples of known color (for example, XYZ tri-stimulus values). An image of the test color sample is then captured using domestically available equipment, such as a consumer digital camera or camera-equipped mobile telephone, the image also containing the color sample capture card. In one embodiment the image is then transmitted to a remote color determination service for color sample color determination. Regression analysis is then performed using the RGB color samples in the image and known XYZ colors thereof to characterize the color capture response of the image capture device. Having characterized the image capture device the XYZ color of the unknown color sample can be determined from the RGB color thereof in the image.

Regression analysis is then performed using the RGB colour samples in the image and known XYZ colours thereof to characterise the colour capture response of the image capture device. In one embodiment the colour calibration characteristics are determined using N known calibration colour samples, wherein N is less than the total number of known calibration colour samples across the whole colour space.

  • Patent number: 6940597
    Abstract: A method for obtaining an approximate standard color definition for a sample color (2) without the need for standard conditions of illumination or observation. The method comprises using color sensing equipment such as a digital camera (6) to sense under non-standard conditions both the sample color and a plurality of reference colors (5) each being provided on a template (1) and each having a known standard color definition. The sensing under non-standard conditions produces a non-standard color definition both for the sample color and for each of the reference colors.
