To investigate the effects of body temperature decrease which occurred along with cold exposure and menstrual cycle, on color sensation, differential limen (DL) and points of subjectively equality (PSE) or red, green, blue and gray colors were measured by using methods of limit in six young female subjects. also, the subjectively preferred complexion was selected. The lowest value in tympanic m...

The Munsell dataset holds a prominent position in the field of color science. This describes large differences covering wide gamut, making it highly valuable for development models. Currently, widely used version is Renotation, which second dataset. In this paper, we analyze third version, known as Re-renotation, identify significant errors within it, and provide corrections obvious typos. We p...

Forensic soil analysis is commonly used to establish a link between collected from suspect (known samples) and crime scene (questioned sample) (1). Taman Tasik Permaisuri located about 7km Kuala Lumpur, one of the capital cities Malaysia. Being densely populated residential place, rate reported also high. Soil most common types evidence encountered in various crimes (2). The understanding varia...

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 di...

PURPOSE To evaluate a customized, portable Farnsworth-Munsell 100 (FM 100) hue viewing booth for compliance with colour vision testing standards and to compare it with room illumination in subjects with normal colour vision (trichromats), subjects with acquired colour vision defects (secondary to diabetes mellitus), and subjects with congenital colour vision defects (dichromats). METHODS Disc...

The traditional techniques of image capture, scanning, proofing, and separating do not take advantage of colorimetry and spectrophotometry. For critical color-matching applications such as catalog sales, art-book reproductions, and computer-aided design, typical images, although pleasing, are unacceptable with respect to color accuracy. The limitations that lead to these errors have a well-defi...

Scores on the American Optical Company (AOC) test (1965 edition), Dvorine test, Farnsworth Lantern test, Color Threshold Tester, Farnsworth-Munsell 100-Hue test, Farnsworth Panel D-15 test, and Schmidt-Haensch Anomaloscope were obtained from 137 men with color-defective vision and 128 men with normal color vision. The validity of each of these tests in predicting scores on the aviation signal l...

Efforts to apply an end-to-end color reproduction system using multi-channel visible-spectrum imaging to a van Gogh self-portrait at the National Gallery of Art, Washington D.C., have been under way at the Munsell Color Science Laboratory. The goal was to perform preliminary experiments by imaging a target consisting of pigments based on direct spectral measurements of the painting. These exper...
