摘要:

A color‐difference formula adapted from the CIE 1976L*u*v* (CIELUV)equation by incorporating the effects of specific viewing and flare conditions is proposed as providing results in better accord with visual experience for the colorimetric evaluation of the quality of the reproduction of a colored object in a scen

摘要:

This article may be incomplete and it may have omissions, but the author has tried his best to research past and present and to describe briefly some of the more important collections of colors assembled to establish graphic records of color identities and color names.

摘要:

A rhombohedral representation of the color solid is described, giving equal prominence to the additive and subtractive basic (primary) colors and to black and white.

摘要:

Selective reflection properties of cholesteric liquid crystals are reviewed. It is then shown that the color of superimposed coatings of these substances is perceived as that of an additive mixture of colors of the coatings. This property permits one to synthesize many spectral reflectance distributions. A greater color gamut than is possible with other colorants can be realized. Applications to visual arts that take advantage of the additive color properties, the highly saturated colors, and the dependence of colors on temperature, angle of illumination, and angle of viewing are discussed.

摘要:

Lìghtness (value), hue, and saturation (chroma) are the three important factors to be considered in the design of a color‐order system. The development of these attributes is traced from 600 B.C. to the present. Special attention is paid to the intrinsic lightness levels of the various colors, which determine their places in color diagrams. The three‐dimensional schematic color perception diagram is described, and its utility for the designer is explained. For the artist this diagram is an important tool, helping him to understand the relationships among the colors in his work. It can aid the scientist in understanding the thought processes of the artist and designer, and in explaining their choice of color placement in a color‐order system. Such a diagram can help everyone understand the natural relationships among

摘要:

The difference in perceived colour caused by placing a colour filter over only a small part of, or over the whole picture area of, a projected slide is used to illustrate the types of measure that are appropriate for evaluating colour appearance in pictures. Psychophysical measures are of limited use, psychometric measures are of more help, but psychoquantitative measures, based on subjective scaling and elaborated on to take account of the effects of absolute luminance levels, are found to be the most appropriate.
