There are well-known and extensive differences in color preferences between individuals,
but there are also within-individual differences from one time to another. Despite the …

The human visual system shows a relatively greater response to low spatial frequencies of
chromatic spatial modulation than to luminance spatial modulation [1]. However, previous …

Although color plays a prominent part in our subjective experience of the visual world, the
evolutionary advantage of color vision is still unclear [1–2], with most current answers …

Colour constancy is the perceptual phenomenon that the colour of an object appears largely
unchanged, even if the spectral composition of the illuminating light changes. Colour …

In the study of the evolution of animal colors, the conspicuousness of a pair of colors (eg,
stimulus vs. background) is often modeled by determining the distance between them in …

Several features of the evolution of eyes and photoreceptors are examined in an effort to
explore the relative roles of adaptation and historical and developmental constraints. Optical …

A central theme of John Lythgoe's book 'The Ecology of Vision'(Lythgoe, 1979) was that of
adaptation: the matching between an organism's phenotype and its natural environment. In …

We summarize direct and indirect effects on fitness components of animal color pattern and
present a synthesis of theories concerning the ecological and evolutionary dynamics of …

This article suggests how we might understand the way potential predators see coloration
patterns used in aposematism and visual mimicry. We start by briefly reviewing work on …

Colour is a critical cue for many vital behavioural tasks: material identification, object
recognition and social–sexual signalling. Given the importance of the behavioural uses of …
