Effect of CIELCH Coordinates on Selection of Preferred Black

In this research the effect of lightness, chroma and hue angle is investigated to select the preferred black among the 216 black fabrics. The rank ordering method was used to visually assess black samples in two steps, i.e., finding the black samples and selecting the preferred black among samples which most of observers detected them as blacks. Performing of 3130 visual assessment experiments shows the effect of hue attribute in blackness perception and preference. In fact, observers mostly selected and preferred the cyanish-bluish blacks while they did not prefer the reddish blacks. Besides, among two blacks with the same chroma and hue angle, the darker one was preferred. For black samples with the same lightness and hues, the blackness preference was related to the sample which is more neutral. Finally, it was found that lightness, chroma and hue angle influence in blackness perception and preference, simultaneously.
