Colour is one of the most important cues used by consumers to assess the quality of a food
product. It may be defined as the individual's response to the visual signals generated by the …

The search for the rules of colour harmony has occupied the thoughts of some of the
greatest artists and scientists. In this article, the main theories of colour harmony are …

The market for fruits and vegetables has received considerable interest in recent years, with
much of its growth attributed to consumer interest in nutrition and health. Quality has been …

The apparent lightness of a surface can be strongly modulated by the spatial context in
which it is embedded. Early theories of such context dependence emphasized the role of …

The perception of color must depend on both sensory and cognitive processes. This chapter
and the next put forward two main arguments. First, that there is a simple and coherent …

White's illusion is the perceptual effect that two equiluminant gray patches superimposed on
a black-and-white square-wave grating appear different in lightness: A test patch placed on …

In classical assimilation effects, intermediate luminance patches appear lighter when their
immediate surround is comprised of white patches and appear darker when their immediate …

Lightness, or perceived reflectance of a surface, is influenced by surrounding context. This is
demonstrated by the Simultaneous Contrast Illusion (SCI), where a gray patch is perceived …

How do induced brightness and darkness signals from local and remote surfaces interact to
determine the final achromatic color percept of a target surface? An emerging theory of …

We masked White's and Benary's brightness illusions and simultaneous contrast with
narrowband visual noise and measured detection thresholds and brightness. The noise was …
