  • Method for representing true colors with device-dependent colors on surfaces and for producing paints and coatings matching the true colors
    Patent number: 7474314
    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.

  • System for Representing True Colors with Device-Dependent Colors on Surfaces and for Producing Paints and Coatings Matching the True Colors
    Publication number: 20080232101
    Abstract: An apparatus for displaying paint colors using device-dependent colors is disclosed. The apparatus has a wall portion sized and dimensioned to be substantially similar to a full size wall, and the device-dependent colors have color coordinates that are substantially similar to the color coordinates of paint colors. Lights displaying the device-dependent colors are diffused before illuminating the wall portion. A method for selecting paints using device-dependent colors is also disclosed.
