- Description
- When red wines are tilted in a glass wine sampler and observed in strong light against a neutral background, the thinner parts appear a shorter wavelength red than the thicker ones. It is discussed whether these hue-shifts, associated with thickness changes, are attributable to simultaneous contrast effects (Bezold–Brucke and Abney effects) or can be detected by conventional instrumental color measurement by spectroradiometer or spectrophotometer (assuming Bouguer's law). The reported hue-shifts at different thicknesses appear to be attributable to both physical-chemical changes and contrast effects. This discussion is in three parts: (1) Color variability of wine in a glass and general comments on contrast effects by Ralph W. Pridmore, (2) Color coordinates of wine samples with different thicknesses by Rafael Huertas, Manuel Melgosa, and Angel I. Negueruela, and (3) Final Comment by Ralph W. Pridmore.
