Interobserver variability and color representation systems

A systematic method of analyzing the colorimetric behavior of a set of observers is proposed. The differences between each observer and a standard one are analyzed with different procedures in two color‐representation systems. It is apparent that these differences strongly depend on the color‐representation system in which they are analyzed. Results obtained in this work indicate that comparison between two observers should be carried out by applying an optimized operator. This operator minimizes the differences between the color‐representation systems associated with the observers that are compared. The proposed method should be applied when color‐matching properties of a set of observers, or when color matching obtained with different colorimetric instruments, are compared. © 2002 Wiley Periodicals, Inc.

The metamerism potentiality of a color recipe

The weighted spectrophotometric color matching method with the optimum weighting to the spectrophotometric equations in each particular wavelength proportional to the viewing condition is applied for minimizing the color difference of instrumental color formulation of textile materials. The work is based on the one‐constant Kubelka–Munk theory. The sensitivity of a recipe to small perturbation of deviation between the reflectance of target and matched samples in the visible spectrum is determined as the metamerism potentiality of proposed recipe. Its correlation with metamerism index was also studied for some metameric pairs. Metamerism potentialities are also appraised under several light sources by using equilibrate matching strategy. The results show that the outputs of colorimetric color matching are exactly identical with the weighted spectrophotometic match under the same viewing condition. According to the numerical results for matching of 58 target samples, there is a good statistical correlation between metamerism indices and the metamerism potentialities of each recipe. Our results show that the quantitative value of the metamerism potentiality of each recipe can reasonably predict the metamerism indices of applied formulation. © 2006 Wiley Periodicals, Inc.

Measurement of memory of color

Colors produced by monochromatic wavelengths of light viewed in isolation have been used as the only visual variables in short‐term delayed matching (DM) and long‐term recall (LTR) protocols to quantify three types of color memory in individuals with normal color vision. Measurements were normally distributed, so that color memories of individuals could be compared in terms of means and standard deviations. The variance of LTR of colors of familiar objects is shown to be separable into two portions, one due to “preferred colors” and the other due to individuals' precisions of matching. The wavelength dependence of DM exhibited minima of standard deviations at the same wavelengths as those reported for color discrimination measured by bipartite wavelength matching, and these wavelengths were shown to occur at the wavelengths of the intersections of cone spectral sensitivities. In an intermediate “green” region of relatively constant color discrimination, it was possible to combine DM measurements for different wavelengths for statistical analysis. The standard deviations of DM for individuals of a healthy population were normally distributed, providing a 95% upper confidence limit for identifying individuals with possible short‐term memory impairment. Preliminary measurements of standard deviations of DM for delay times of ≤ 1 s were consistent with a proposed rapidly decaying color imagery memory. © 2002 Wiley Periodicals, Inc.

A novel approach to color matching of automotive coatings

The coatings industry requires a fast and accurate color formulating process. Today the manual/visual color matching procedures are time consuming and require high skills, in particular when metallic and pearlescent colors are involved. For that reason, a new approach to the colorimetry of paints was followed. This resulted in the development of a system employing an easy to use instrument and powerful software allowing instant formulation of almost any desired color. The system comprises a portable multi-angle spectrophotometer in combination with a personal computer and dedicated color matching software. Development of both the instrument and the software resulted from research on optics, vision science, color mixing properties and computational procedures. In the software new algorithms describing the light-paint interactions (absorption and scattering) and the procedures applied at on site color matching are imbedded. The system retrieves the optimum paint formula through fully automated multi-angle spectral measurements followed by an analysis of the spectra and subsequent data bank search. When desired, correction procedures allow adjustment of the formula through additional measurements on a spray out sample.     

Familiar objects and memory color

Memory color for a set of eight different familiar objects has been investigated. Our results obtained with one hundred observers, eighty color samples of NCS, and two illuminants indicate that: (a) the shifts that are produced in the dominant wavelength with memory depend on the familiar object considered; (b) colorimetric purity, as a measure of saturation, of the remembered objects is not the same as that of the familiar objects; (c) in the SVF representation space, with illuminant D65 and regardless of experience in color matching of the observer, the color that was best remembered was purple aubergine and the worst remembered was brown chestnut. With the illuminant A, red tomato was the best remembered color and yellow lemon the worst. © 1998 John Wiley & Sons, Inc. Col Res Appl, 23: 416–427, 1998

Visual color matching under various viewing conditions

In this article, we provide colorimetry data for which it was judged that the colors between different media matched under various viewing conditions. Painted color patches, a monitor, and printed color patches were used in the color matching experiments, in which we compared the appearances of the painted color patch and the monitor, or the monitor and the printed color patch, using the method of constant stimuli. The nine types of viewing conditions we used could be envisaged to occur when comparing different device outputs indoors. The experimental data obtained were compared with corresponding colors predicted with the use of five types of color appearance model, including color appearance formulae. We found that when the viewing conditions were the same for the different media, there was good agreement between the experimental data and the CIECAT94 model. And by adjusting the brightness induction and the chromatic induction factors, it was possible to improve conformity for the lightness and the chromaticity. Moreover, it was possible to improve the white point shift, which cannot be adjusted with the use of optimized parameters by introducing incomplete adaptation. By optimizing the parameters and introducing incomplete adaptation, it is possible to make the mean color difference ΔE between the corresponding color and the color matching point less than 10 CIELAB units for all of the viewing conditions.
