摘要:

AbstractImportant modern color order systems accompanied by physical exemplifications (atlases) are surveyed; one of great historical interest, though not currently available, is included. The systems covered include the Munsell, Natural Color, OSA‐UCS, DIN, Coloroid, and Ostwald systems. Their history, guiding principles, variables, and relation to the CIE system are described. Some of the interrelationships among the systems are then considered, specifically those between the Munsell system and the Natural Color and OSA‐UCS systems. Implications for the consideration of international standard color order systems are mentio

摘要:

AbstractFor the evaluation of color design, a multiple linear system analogous to the human visual perceptual system was proposed. Using computer‐generated random color patterns, a psychological test was performed and its results were analyzed in terms of the Fourier transform of the color patterns. It was clearly concluded that the power spectrum obtained by the Fourier transform of the patterns had characteristic meanings at regions of very‐low, low, medium, and high spatial frequenc

摘要:

AbstractColor atlases, such as those based on the theories of Ostwald and Munsell, are useful because they simplify finding the color one has in mind for a specific use, not because the colors in the scales have a harmonious relation that can be used without further consideration. The author believes it is the orderly sequence that gives this impression. Other limitations of the atlases are discussed. Selecting harmonious colors is a creative process that considers the design, and fashions and mores of the times, and the changing character of the arts. Looking at color usage everywhere seems the best way to learn and understand color harmony.

摘要:

AbstractThe methods used by the Scottish Museum of Tartans for recording the yarn count and color specifications of tartans are described. The origin of the colors used in old tartans has been investigated by preparing dyeings on wool using extracts from a large number of plants native to Scotland. The colors so obtained have been recorded, and a selection of the results is presented in terms of CIELAB coordinates and compared with the colors obtained from the well‐known natural dyes of the past. The changes in color caused by fading have also been recorded and the results analyzed to clarify the origin of the colors used in the modern, ancient, and reproduction tartans manufactured toda

摘要:

AbstractThe color behavior of unconventional colorant systems and certain other mixtures cannot be described adequately by available theory. In such cases alternative approaches to formulation and shading need to be developed. In this article we investigate empirical models using Scheffé polynomials to describe color response surfaces for three‐ and four‐component olorant mixtures. We describe experimental designs that allow the efficient estimation of the coefficients of high‐order polynomial models over the full mixture‐design space and that also allow estimation of lower‐order models over subspace mixture regions. The experimental designs are applied to real colorant systems, and the accuracy of color response prediction from linear, quadratic, cubic, and quartic polynomial models is compared to that of theoretical models. The color response surfaces are visualized by preparing contour plots that depict color variation over a compositional region. These maps allow one to observe the relationship between color and composition, to assess the color gamut available with a given colorant set, and to estimate the formula or adjustments required to match a given color position. The effective use of model predictions to perform a sensitivity analysis on the compositional variables is also demonstrated in the context of manufacturing proce
