Resumen
Valid and traceable instrumental measurements of all the visual attributes that characterize the appearance of a material (color, gloss, texture and translucency) are necessary to ensuregood product quality control. The objective of this work is to evaluate the visual attribute of texture associated with special effect pigments in order to be able to establish a measurementscale. In particular, this study evaluates the influence of the hue of absorption pigments on the perception of graininess. For this purpose, nine samples with a systematic variation of hue anglewere used. A visual experiment based on the comparison of triplets was designed, and a multidimensional scaling (MDS) analysis was applied to obtain relative values of perceivedgraininess. The results confirm that the hue angle of the absorption pigments does not influence the perception of graininess.
