摘要:

AbstractThis article describes the design, construction, and evaluation of a visual colorimeter for use in studies of color perception in the natural environment. The colorimeter is portable, has a low power consumption, and produces luminances typical of those found outdoors. An asymmetric binocular‐matching procedure is used to match the colors of natural objects. The performance of the colorimeter was tested by comparing chromaticities of matches of colored papers to spectrophotometric measurement

摘要:

AbstractThe ability of observers to discriminate between five types of fluorescent lamps on the basis of the colour of their own skin has been compared to their ability to make the same discriminations on the basis of four arbitrary object colours and a single grey object colour. The results have been analyzed by various statistical tests, which indicate clearly that skin colour provides a more sensitive indicator of colour rendering than do the other two targets. Multidimensional scaling analyses show that discriminations between the five lamps can be represented in a two‐dimensional space. The first and more important dimension apparently represents the warm‐cool dimension of the colour of the lamps, and the second dimension is related in some way to the colour of objects illuminated by the lamps.Observers were also asked to rate their preferences for the redering of their skin under five lamps. Statistical analysis of the results shows that preference varies from observer to observer and to some extent with experience. Some general trends are evident but detailed analysis of preference in terms of the two‐dimensional space derived from the discrimination results will require more study with a greater variety of

摘要:

AbstractFuzzy as well as statistical operations are performed to illustrate potential usages of the membership functions of the surface colors of apaque materials obtained through the fuzzy statistical experiment. The method is examplified by the color selection procedure in product design. The degree of association between colors and visual perception about colors is investigated through correlation analysis. The fuzzy membership functions and the associated statistical method provide a natural basis for the quantification of a qualitative relation about colors.

摘要:

AbstractSystematic collections of colour samples from colour order systems are used in many cases, e.g., in architecture and in design. Usually, the colour that a designer has in mind is not found as a colour sample within the collection at hand, but has to be determined by visual interpolation between the available samples. However, because the colour coordinates of the available samples deviate from those of the aim points, these deviations give rise to uncertainties during visual interpolation.I have investigated the influence of the colorimetric accuracy of the colour samples in the collection used on the precision of colour notation by visual interpolation. This research shows that the accuracy of notation by visual interpolation is not influenced by the colorimetric precision of the colour collection alone, but also by the magnitude of the colour differences between adjacent colour samples in the respective colour collection and by the directions of the colour differences from the aim points.

摘要:

AbstractIn 1985 a research program was instigated to determine the feasibility and desirability of developing a computer based colour notation conversion program. Results indicated that the development of such a program covering the Munsel, NCS, DIN, OSA‐UCS, Coloroid, CIELAB and CIELUV colour specification systems for use as a research tool was both feasible and desirable. The program was completed early in 1989 and this is the first of a number of articles that uses this program as a research tool. The colour notation conversion program has been used to evaluate the accuracy of the samples which comprise the NCS, DIN and OSA‐UCS colour atla
