Validation of displays for displaying reference colors

A method for scoring color accuracy of color output devices relative to a set of discrete color standards represented in a two-dimensional array, each color standard comprising reference spectral or colorimetric information, the method comprising:

• causing a color output device to generate a plurality of discrete colors, each generated discrete color having a corresponding target color within the set of discrete standard colors;
• measuring the generated plurality of discrete colors;
• for each color measurement, determining color differences between the color measurement and the 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;
• 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;
• wherein the score for color precision average comprises determining whether the closest match for each generated color is its corresponding target color, a color adjacent to the target color, or a color not adjacent to the target color in the two-dimensional array.
