摘要:

AbstractThe way each of us uses color reveals a lot about ourselves. Color may be used unconsciously or consciously. In either case, color provides the trained observer with important cues regarding the nature of inner conflicts in a patient or client. Our liking or disliking of any color is associated with information received from significant persons. In most cases, this association is related to status, our desire to improve our position within some social scale. The deceptive use of color and the concept of sophisticated color seem to be interdependent.

摘要:

AbstractEnergy transfer between fluorescent organic pigments (fluorophors) dispersed in a paint vehicle was studied for mixtures of a yellow, a red, and an orange fluorescent pigment, and for mixtures of these with titanium dioxide. Radiative energy transfer occurs among the fluorophors, but not between them and titanium dioxide A shift to longer wavelengths of the emission peak of a fluorophor with increasing paint‐film thickness was noted and was ascribed to reabsorption and reemission of fluoresced radiation within the overlapping excitation and emission region typical of these organic fluorophor

摘要:

AbstractThe wavelength interval 360‐830 nm relevant in colorimetric computations is sometimes truncated by the instrument used to measure the spectral characteristic of a material, or the spectral power distribution of a source, or simply by choice. The (systematic) error resulting from this truncation has been derived. Tables are given for the calculation of the truncation error in each cas

摘要:

AbstractA method of color control of bulk‐dyed cellulose acetate is described, based on the transmittance spectrum of the dope. Control can be effected only if the spectrum is recorded from thick samples which amplify the absorption from small amounts of impurities that later cause unacceptable color differences on the yarn. The calculation of the reflectance spectrum, and hence the color, of the yarn from the transmittance spectrum of the dope by Kubelka‐Munk theory is not satisfactory due to faint turbidity of the ‘bright’ dope. The reflectance spectrum of the yarn can be calculated from a series expansion of the experimental Lambert law absorption coefficient with very satisfactory results. A fully computer‐managed color‐control method is employed successfully in industri

摘要:

AbstractModerate (0.5–1.5 CIELAB units) color differences in surface colors were scaled visually to obtain color‐dif‐ference‐perceptibility ellipses. The ellipse orientations appeared to be independent of the size of the color differences over the range indicated, and were consistent with literature results obtained with visual colorimeters. In the uivid greenish yellow region, the experimental ellipse orientation agreed with the Munsell spacing but not with the orientation of the CIELAB ellipse. In the deep greenish blue region, the experimental ellipse orientation agreed belter with the results of Wyszecki and Fielder than with the orientation of the MacAdam PGN

摘要:

AbstractThis article describes the techniques for measuring specular (regular) reflectance of mirrors on an absolute basis. Two independent methods of measuring mirrors are described, and data are presented for the two methods of measurement in the range 400–1500 n

摘要:

AbstractA method of measuring and comparing the greyness (unwanted spectral absorptions) of process colorants has been developed. The method uses the 1976 CIELAB color space and, in effect, makes a chromatic match of a trial colorant with a reference Cromalin®‡color and then calculates greyness from the difference of their values of CIE 1976 lightness

摘要:

AbstractThe method of singular‐value decomposition analysis of matrices is used to analyze the 20 color‐matching functions of Stiles's observers. It is confirmed that the 20 color‐matching functions are well reconstituted by the first three decomposed components. A new deviate observer is derived from the first decomposed component. It is shown that the new deviate observer can be used well in the computation of observer‐metamerism indices. Furthermore, an optimized deviate observer is developed by modifying the color‐matching functions of the new deviate observer slightly. Both the new and the optimized deviate observer give a basis for the further study of the evaluation of observer m
