Each hue is believed to be made up of the four component hues (yellow, blue, red, and green). A hue consisting of just one component hue is called unitary (or unique). A new technique--partial hue-matching--has been used to reveal the component and unitary hues for a sample of 32 Munsell papers, which were illuminated by neutral, yellow, blue, green, and red lights and assessed by four normal t...

The pomegranate fruit is a good source of bioactive compounds. The present study has investigated the biochemical and sensory characteristics of the arils of four Iranian commercial pomegranate cultivars namely Malase Shirine Saveh (MSS), Malase Torshe Saveh (MTS), Alak Shirine Saveh (ASS) and Agha Mohammad Ali (AMA) for several developmental and ripening stages during 45–180 days after fruit s...

Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sam...

This study examines the equivalence of the City University color vision test (CUT) to the Farnsworth Munsell D-15 (D-15). This information is important because a number of occupations require individuals to pass either the D-15 of the CUT. Using two or more major crossings on the D-15 as failure, our results indicate that agreement between tests can be improved if the failing criterion for the ...

In the composition, analysis and evaluation of artworks, an understanding of colour is of high importance. Colour is commonly understood in terms of its perceptual components: hue, saturation and lightness. Of these, it is within the hue values of an artwork that many of their high-level aesthetic dimensions are found and it is through the global contrast of hue by which these dimensions are be...
