Precise colour description results in a better classification and evaluation of wood products. Two systems of colour determination were applied and compared in 98 Amazonian wood species: the Munsell colour system, a visual determination comparing colour standards with samples, and the DIN colour chart using a reflectance reading colorimeter. The Munsell system is sufficient, when applied in simple descriptions of wood colour. To evaluate variations and changes in colour, however, the method of reading the colorimeter and converting to the DIN colour chart is recommended. This method allows the user to calculate precisely differences between colours.

The scientific literature dedicated to the analysis of peculiarities of the soils colouring and interconnection the genetic horizons colour as well as separate morphological elements with their properties have been analyzed. The identification of colour of genetic horizons in 20 profiles of brownish-podzolic gleyed soils of Ukrainian and Polish Precarpathians has been conducted. The colour of investigated genetic horizons and separate morphological elements was determined according to both national and international systems. The analysis of the appropriateness of national approaches rejecting and usage of the Munsell scale as a primary method for determining the soil samples colour has been carried out. The results of the survey of the respondents with different professional training ascertained that visual determination of colour range within morphological description of the soil is completely subjective. The correctness of procedure depends on the experience of soil scientists and colour homogeneity of the soil sample. Using of the Munsell scale reduces the errors in the determination by 70–80 %, which allows recommending the very approach as the principal one for the field descriptions. Change of the investigated soils colour depending on the level of humidity has been established. The peculiarity of soil mass colour range depending on the aggregation and fractions size has been found out. Based on the colouristic analysis it has been confirmed that chemical and mineralogical composition is the main factor of heterogeneity of the investigated soils horizons colour. It has been found out that heterogeneity of the colour range, and the appearing of bleached zones (as the result of iron removing) and fine dust on the surface of the aggregations is associated with gleying processes, impulse redox regime and metamorfization of soil mass. It has been established that interdependence between the complex of statistical and fractal parameters, which indicates the relative optical heterogeneity of architectonics of the investigated soils ultra thin cuts which are characterized by optical heterogeneity on the macro-level. The processes of morphogenesis of self-similar elements of their architectonics cause the asymmetry and fluctuations of relative data and increasing of the half-width of the autocorrelation functions of orientation tomograms. Red and green shades are shown to be the basic components of the sample colour. Red ones are determined by red colour pigments, and the combination of red and green shades provides the formation of yellow tones. The possibility of data conversion from the Munsell system into the CIE-L*a*b* system with minor deviations has been shown. 2,5Y5 / 4 in Munsell system corresponds to the following data in the CIE-L*a*b* system: L* = 41,23; a* = 5,59; b* = 20,06 (manual calculation) and L* = 41,22, a* = 4,97, b* = 19,44 (automatic transfer using the computer program Munsell Conversion 4.01).

The Abney effect in colour-appearance systems (Munsell, NCS) means that the lines for identical apparent hue (at constant lightness) do not coincide with the straight lines for constant dominant wavelength. The curvature of constant-hue lines in chromaticity diagrams reflects the fact that cone signals are nonlinear functions of the rate of photon absorption. The most widely used nonlinear intensity-response function in vision is the Naka - Rushton function, which in an intermediate range can be approximated by a square-root function. Our purpose has been to study the Abney effect in the Munsell and NCS colour atlases in order to develop a mathematical-physiological description on this basis, designing the redness - greenness and yellowness - blueness perceptual variables and the perceptual hue function in each colour system. The description is applicable to both biological and machine-vision systems.

A problem of qualitative determination of the results of colour image capturing by digital devices based on uniform colour systems arises during analysis of colour images. The article describes methods of determining colour difference as recommended by CIE for the CIELAB system, presents mathematical formulation of the system and its modifications, describes the programme developed for calculating colour difference for each described method, and describes testing of this programme using 14 sample colours from the Munsell Book of Colour. Three groups of red, green and blue filters with 7 filters in each were selected as the study object. The filters were selected based on possibility of their further application for determining colour shift by digital devices. Filter colour difference was studied in the groups with different standard sources of light and using three methods of calculation of this difference. Analysis of the obtained results is presented and conclusions are made on possibility to apply each method in different industrial spheres. The article may be useful for colour analysis specialists, quality inspectors and specialists in digital devices and computer vision.

In studies of sexual selection in birds, it is necessary to quantify the conspicuousness and sexual dimorphism of the plumage. We present a method, based on the Munsell colour system, that is easier to use than spectroradiometric techniques. It is based on measurable and repeatable data, although it is dependent on human vision. It provides indices of sexual dimorphism and incorporates aspects of close-range and long-distance conspicuousness. Ten species of Emberezidae were chosen to illustrate the procedure, and it was tested using naive observers. It consists of dividing the body of a bird into regions and matching the colour of each region to chips in a colour guide. The following indices based on the parameters of the Munsell system were selected: value (V), chroma (C), and Munsell power (V∙C), which measure conspicuousness independently of the background; Wv, Wc, and Wv∙c, which measure the contrast between the colours in the plumage; Bv, Bc, and Bv∙c, which measure the contrast between the bird and its background; and Dv, Dc, and Dv∙c, which are the indices of sexual dimorphism of the plumage. There was a high degree of agreement among the naive observers, and the scores obtained using field guides did not differ significantly from those recorded on museum specimens. One of the dimorphism indices (Dv∙c) was found to give more information than the others. However, our results indicate that conspicuousness and dimorphism indices should not be used individually because they are interdependent, and that they should be used in conjunction with multivariate analyses. Also, the proposed method incorporates long-distance conspicuousness into the results.

Colour constancy is a multi-stage process whose receptoral and post-receptoral components have been separated by electrophysiological and behavioral studies. A psychophysical study was conducted to determine contributions of the visual processing stage which extracts information about colour categories, and to relate the results to the spectral sensitivity of the chromatic opponent system. Changes in colour appearance with illumination were investigated by using free-viewing and a successive matching method for 40 Munsell hues (saturations: 8 and 4). Subjects were adapted to standard illuminant C and briefly inspected a test chip under a variable illuminant A (tungsten) or g (green). Using criteria similar to those for unique hues, subjects specified ‘typical hues’ under illuminant C: red, yellow, green, blue, and violet (yellow should not contain red or green, green should not contain yellow or blue, etc). For each hue and saturation a dominant wavelength was computed. The degree of colour constancy was then established for all subjects (examined in three series of experiments), all Munsell chips and illuminations, as a one-dimensional Brunswick ratio, BR. The BR was determined by using u‘ v’ coordinates as related to the ratio of perceptual to physical colour changes: BR=1-perceptual/physical. BR was highest for typical (not intermediate) hues and lowest for hues resembling variable illuminants. The BR as a function of dominant wavelength resembles the spectral sensitivity function of chromatic opponency. These findings are interpreted as contributions of high-order opponent interactions to colour constancy.

The study aims to achieve an understanding of the artist’s materials and techniques used by Lucky Madlo Sibiya when he created his carved and painted wood panel artworks. A survey of the artist’s materials and techniques is of great importance, because he is represented in multiple institutional, corporate and private collections – including the University of Pretoria. His carved and painted wood panel artworks are also reaching an age (at least 20 years old, as 2019 is the twentieth anniversary of his death) when they would soon require conservation and restoration, if not stored and displayed according to sound conservation conditions and standards. For best-practice conservation and restoration, in-depth knowledge of the materiality of an artwork is needed. In order to reach an in-depth knowledge of the materiality of Sibiya’s carved and painted wood panel artworks, the survey intends to examine and document through the combination of various historical, visual and analytical techniques artworks with unrefuted provenance. The analytical techniques used are popular in heritage conservation, because they are non-invasive and non-destructive. They include provenance studies, visual examination, technical photography, X-ray Fluorescence and Fourier-transform Infrared Spectroscopy. In combination, the techniques should reveal the materials and techniques Sibiya employed. This knowledge will be used to safeguard and preserve this part of South African art heritage.

博士 高雄醫學大學 牙醫學研究所 101 As we pay increasing attention to dental aesthetics, tooth color matching has become an important part of daily dental practice. But measuring tooth color with dental shade guides by human eyes is not stable because of the inadequate design of the dental shade guide and the poor reliability of human eyes. The tooth color measuring machines provides another choice when dentists make the shade selection, but the accuracy of these machines is still controversial. The aim of this study is to combine the usage of the proper tools and conclude method which enhances the accuracy of tooth color measuring. The Munsell color tabs within the range of natural human teeth color were measured by three tooth color measuring machines (ShadeEye NCC, VITA EasyShade, DeguDent Shadepilot). The results showed when Chroma was higher than 6, and Value was lower than 4, the mean ΔE measured by ShadeEye NCC was significantly higher than the clinical acceptable range. When Hue located in 7.5YR and 10YR,Value was higher than 7, the mean ΔE measured by EasyShade was significantly higher than the clinical acceptable range. The measuring results of Degudent Shadepilot showed no significant different with Hue, Chroma, and Value, but when Hue located between 10YR to 10Y, Value located between 5 to 7 and Chroma was 2 and 6, Degudent Shadepilot showed better accuracy.
As we know the limit of each dental color measuring machine by the procedure in this study, we could combine the usage of each machine and help us to achieve the optimal tooth color measuring result in daily dental practice.

AbstractColor planning has become a significant issue in urban development, and an overall cognition of the urban color identities will help to design a better urban environment. However, the previous measurement and analysis methods for the facade color in the urban street are limited to manual collection, which is challenging to carry out on a city scale. Recent emerging dataset street view image and deep learning have revealed the possibility to overcome the previous limits, thus bringing forward a research paradigm shift. In the experimental part, we disassemble the goal into three steps: firstly, capturing the street view images with coordinate information through the API provided by the street view service; then extracting facade images and cleaning up invalid data by using the deep-learning segmentation method; finally, calculating the dominant color based on the data on the Munsell Color System. Results can show whether the color status satisfies the requirements of its urban plan for façade color in the street. This method can help to realize the refined measurement of façade color using open source data, and has good universality in practice.
