Abstract: A method for scoring color accuracy of color output devices relative to a set of discrete color standards comprises causing a color output device to generate a plurality of discrete colors; measuring the generated plurality of discrete colors; for each color measurement, determining color differences between the color measurement and corresponding reference spectral or colorimetric information for the discrete color standards; scoring the color output device based on weighted scores for color precision, average color difference between a generated discrete color and its corresponding target color, and highest individual color difference between a generated discrete color and its corresponding target color; and for each generated color, determining a closest matching discrete standard color by identifying the discrete standard color having the lowest color difference from the generated color's measurement.

Abstract: A color measurement instrument for measuring colors of areas of interest of a target object includes a spectral engine, a color camera, a display, and a processor. The spectral engine has a first field of view. The camera has a second field of view, the second field of view being larger than the first field of view and encompassing the first field of view. The processor is coupled to the spectral engine, camera and display, and configured with instructions that, when executed, cause the processor to display a live view of the second field of view on the display with a representation of the location of the first field of view superimposed on the displayed live view, an area of interest is detected as wholly occupying the first field of view, and a measurement is made.
