Abstract:
Ten process-printed color charts based on the perceptually ordered Munsell system were previously developed. Sixteen cartographers with experience in color map design were mailed copies of the chart and were subsequently interviewed by telephone. The objectives of the interviews were to gather background information on the cartographers' general use of color charts and to examine the perceived usefulness of the Munsell-based charts as aids for map color selection. Approximately half of the interviewees were not satisfied with the color charts they were currently using. Over half of the cartographers had difficulties with differences between printed map and chart colors. As a summary of the interviews, eleven recommendations are made for the design of yellow-magenta-cyan charts of the conventional lithographers' format. Twelve of the cartographers judged the Munsell-based charts as potentially useful aids for map color selection, especially for the design of thematic color progressions. Likewise, the cartographers' solutions to di ffic ulties with the layouts of their conventional charts indicated that a different chart organization, possibly perceptual, would be useful to cartographic designers. Overall, the interviews revealed a surprising diversity of opinions about and requirements of color charts that are used in map design.

Abstract:
To establish the relationship between the intensity of the green color of leaves and their crude protein (CP) concentration in Urochloa brizantha, U. decumbens and U. humidicola pastures in the Piedemonte Llanero, Colombia, the leaf chlorophyll concentration was measured (in SPAD units), classified based on the Munsell color chart and compared with the leaf CP concentration determined by the Kjeldahl method. The regression analysis between chlorophyll and CP concentrations showed coefficients of determination (r2) between 0.76 and 0.88. While collection of additional data will allow colorimetric charts based on the Munsell color chart to be developed which can be used to predict CP levels for each of these species, the relationships generated can be used to develop recommendations to assist farmers in the region in their decisions on use and fertilizing of these pastures.

Abstract:
Salah satu sifat tanah yang paling sering digunakan oleh para peneliti untuk menggambarkan dan mengklasifikasikan tanah adalah warna. Warna merupakan sifat fisik yang dapat memberikan informasi tentang beberapa karakteristik paling penting dari suatu tanah seperti, komposisi mineral, usia, dan proses pembentukan. Dengan mengetahui warna dari suatu tanah, maka dapat ditentukan kegunaan tanah tersebut apakah cocok untuk lahan pertanian, perkebunan, perumahan, dan lain sebagainya, disesuaikan dengan kondisi tanahnya. Dalam mengidentifikasi warna tanah, para peneliti menggunakan standar warna pada buku Munsell Soil Color Chart. Banyaknya variasi warna pada buku ini menyebabkan peneliti membutuhkan kecermatan dan waktu lama dalam penentuan warna tanah. Keterbatasan indera penglihatan manusia juga mampu menjadi faktor terjadinya kesalahan sehingga informasi yang diperoleh menjadi kurang akurat. Oleh karena itu, dikembangkanlah aplikasi menggunakan pengolahan citra digital untuk mengidentifikasi warna tanah berdasarkan Munsell Soil Color Chart menggunakan metode Support Vector Machine (SVM) dan ekstraksi fitur warna Modus dan Mean. Proses diawali dengan melakukan cropping terhadap citra tanah inputan menjadi 170x200, kemudian mengurangi noise pada citra masukan menggunakan median filter dan mengekstraksi fitur dengan Modus dan Mean. Selanjutnya proses training dan testing data menggunakan metode SVM. Pengujian yang dilakukan menghasilkan tingkat keakuratan mencapai 93,33% untuk masing – masing ekstraksi.

Abstract:
Penentuan warna tanah tidak mudah karena banyaknya jenis tanah dan tingginya tingkat kemiripan warna tanah. Untuk mengatasi kesulitan ini, para praktisi menggunakan suatu buku pedoman warna tanah yaitu <em>Munsell soil color chart</em> (MSCC). Penelitian ini bertujuan mengembangkan aplikasi mobile untuk mengidentifikasi warna tanah dalam menentukan warna mayor tanah sesuai buku MSCC. Aplikasi dibangun menggunakan pemodelan warna HVC dengan komponen warna <em>hue</em>, <em>value</em>, dan <em>chroma</em>. Penelitian ini menekankan klasifikasi untuk warna <em>hue</em> saja. Meskipun demikian, diteliti juga komponen warna <em>value</em> dan <em>chroma</em>. Citra yang digunakan sebagai data latih adalah 259 citra dari buku MSCC yang masing-masing berukuran 1600 piksel. Data warna <em>hue</em> dari setiap piksel ini dianalisis dalam bentuk histogram dan diklasifikasikan dengan KNN. Hasil penelitian menunjukkan bahwa akurasi tertinggi dalam klasifikasi nilai <em>hue</em> adalah 45% pada nilai <em>k</em> = 5. Akurasi mungkin dapat ditingkatkan dengan cara menggunakan data <em>soil color</em> yang sudah tersedia secara <em>online</em>.<br /><br />Kata kunci: Android, HVC, KNN, <em>Munsell soil color chart</em>.

Abstract:
The purpose of this paper was to evaluate achromatic and chromatic vision of workers chronically exposed to organic solvents through psychophysical methods. Thirty-one gas station workers (31.5 ± 8.4 years old) were evaluated. Psychophysical tests were achromatic tests (Snellen chart, spatial and temporal contrast sensitivity, and visual perimetry) and chromatic tests (Ishihara's test, color discrimination ellipses, and Farnsworth-Munsell 100 hue test—FM100). Spatial contrast sensitivities of exposed workers were lower than the control at spatial frequencies of 20 and 30 cpd whilst the temporal contrast sensitivity was preserved. Visual field losses were found in 10–30 degrees of eccentricity in the solvent exposed workers. The exposed workers group had higher error values of FM100 and wider color discrimination ellipses area compared to the controls. Workers occupationally exposed to organic solvents had abnormal visual functions, mainly color vision losses and visual field constriction.

Abstract: The objective of this work was to estimate the iron oxide contents (hematite and goethite) and to characterize the color and the spectral and magnetic signatures of Cerrado soils in the state of Goiás, Brazil. Six Oxisols and one Inceptisol were studied. Spectral and magnetic signatures were determined by diffuse reflectance spectroscopy (DRS) and magnetic susceptibility, respectively. Then, the spectral curves and the second derivative calculations were used to determine hematite and goethite contents, as well as soil color after conversion into tristimulus values. Hematite and goethite contents were also obtained by x-ray diffractometry, and soil color was also defined in the field (Munsell color chart). The values for the isomorphic substitution of iron by aluminum and the degree of redness were also determined. DRS can be used to estimate hematite and goethite contents, as well as the color of Cerrado soils in the state of Goiás. The spectral signature can point out the main soil properties related to the contents of organic matter, iron oxides, kaolinite, and gibbsite. The magnetic signature, characteristic of soils rich in iron oxides (hematite and goethite), shows the predominance of pedogenic minerals.

Abstract:
The establishment of appropriate standards related to the physiological and morphological aspects of the seeds are fundamental procedures to help the nurserymen and seed producers in determining the maturity and the appropriate moment of collection of the fruits. In this sense, the objective of this research is to evaluate the physiological maturation of seeds of Parapiptadenia rigida by means of germination and vigor tests, based on the color of the pods. The seeds were collected in June 2017, from three matrices located in the municipality of Marechal C&acirc;ndido Rondon, Paran&aacute;, Brazil. The pods were classified in four stages of maturation, according to the Chart of colors model &ldquo;Munsell colors chart&rdquo; for plants tissues, and measured the biometric parameters. The parameters observed to evaluate the germinative potential are: first germination count, germination velocity index, emergency velocity index, and fresh and dry matter masses of seedlings. The experimental design was completely randomized, with five maturation stages and four replicates of 25 seeds each. The averages were compared using the Tukey test at a 5% probability. The germination test showed that the increase in physiological potential of P. rigida seeds is associated with the progresses of pod maturation. Therefore, the vigor test demonstrated that the physiological maturation of the species is simultaneous with the change of coloration and maturation of the pods.

Resumo: Padrões de cores Munsell são muito utilizados como referência de cor em diversos campos da ciência. O presente estudo partiu da dificuldade do ajuste de cores na indústria de tintas, o que constitui um problema técnico, pois os profissionais que se relacionam com os clientes e os próprios clientes desconhecem as dificuldades de reproduzir as cores. Neste estudo, analisaram-se as diferenças de cores Munsell de mesma notação, mas adquiridas em diferentes datas. Entre os exemplares Munsell analisados estão: dois livros do The Munsell Book of Colors, o primeiro adquirido em janeiro de 2005, e o segundo, em dezembro de 2006, folhas Munsell adquiridas em setembro de 2004 e duas cartelas Munsell Neutral Value Scale, ambas adquiridas em dezembro de 2006. Todos os padrões analisados apresentavam o acabamento brilhante e foram adquiridos do mesmo fornecedor. Foi medida a diferença de cor através do espectrofotômetro Datacolor, em vinte cores e a análise visual foi realizada na cabine de luz BYK Gardner. Para aproximadamente 70% das amostras de cores Munsell analisadas, existe uma diferença de cor perceptível entre aquelas de mesma especificação. Os valores encontrados não tiveram constância de resultados, pois amostras mais antigas apresentaram valores de diferença de cor menores que amostras mais novas. Recomenda-se aos usuários de cores Munsell façam uma avaliação da cor de suas amostras para controlar o estado do seu exemplar. Concluiu-se que o Munsell têm variação entre as amostras de cores produzidas, e que essa variação pode interferir na análise do controle de qualidade de cor na indústria. As causas destas variações nos atributos da cor Munsell são desconhecidas, mas sabemos que o impacto no cliente que recebe a cor é grande, pois não se sabe se a cor que está sendo utilizada confere com as especificações, podendo até gerar conflitos se as partes interessadas não entrarem em acordo
Abstract: Munsell color charts are widely used as color reference in many science fields. This study was motivated by the difficult to match colors in the industry of paints, what constitute a technical problem, due to the fact that professionals that work with customers and customers don¿t know the difficulties of reproducing colors. In this work, we measured Munsell color differences with the same notation, but bought in different dates. Among them are; two ¿The Munsell Book of Colors¿, the first one was bought in January 2005, the second one in December 2006, Munsell sheets bought in September 2004 and two ¿Munsell Neutral Value Scale¿ charts, which were bought in December 2006. All colors analyzed were in glossy finish and were bought from the same supplier. The color difference was measured by a Datacolor spectrophotometer in twenty colors and the visual analyze was done in a BYK Gardner light booth. As a result we found that for more than 70% of Munsell colors samples, there are a perceptive color difference among the ones which has the same specification. The obtained values show no constancy in the results, due to the fact that old samples had smaller results than the new ones. Is recommended to users of Munsell to do a color analyze in their samples, in order to estipulate the tolerance and to control the color. This work concludes that Munsell have colors variations which can interfere in the quality color control of industries. The causes of color variations are unknown, but the impact in customers who receives the color is high, which can cause conflict if both parts do not find a compromise

Abstract:
In the terrestrial biosphere forests have a significant role as a carbon sink. Under recent climate change, it is increasingly important to detect seasonal change or ‘phenology’ that can influence the global carbon cycle. Monitoring canopies using camera systems has offered an inexpensive means to quantify the phenological changes. However, the reliability is not well known. In order to examine the usefulness of cameras to observe forest phenology, we analysed canopy images taken in two deciduous forests in Japan and England and investigate which colour index is best for tracking forest phenology and predict carbon uptake by trees. A camera test using model leaves under controlled conditions has also carried out to examine sensitivity of colour indices for discriminating leaf colours. The main findings of the present study are: 1) Time courses of colour indices derived from images taken in deciduous forests showed typical patterns throughout the growing season. Although cameras are not calibrated instrument, analysis of images allowed detecting the timings of phenological events such as leaf onset and leaf fall; 2) The strength of the green channel (or chromatic coordinate of green) was useful to observe leaf expansion as well as damage by spring late frost. However, the results of the camera test using model leaves suggested that this index was not sufficiently sensitive to detect leaf senescence. Amongst colour indices, Hue was the most robust metric for different cameras, different atmospheric conditions and different distances. The test also revealed Hue was useful to track nitrogen status of leaves; 3) Modelling results using a light use efficiency model for GPP showed a strong relationship between GPP and Hue, which was stronger than the relationships using alternative traditional indices.
