Color is famous for not existing in the external world: our brains create the perception of
color from the spatial and temporal patterns of the wavelength and intensity of light. For an …

Color has become a premier model system for understanding how information is processed
by neural circuits, and for investigating the relationships among genes, neural circuits, and …

The perception of colour is a central component of primate vision. Colour facilitates object
perception and recognition, and has an important role in scene segmentation and visual …

A primary goal of the visual system is to make sense of the distribution of light that reaches
the retina, in order to guide one's actions in the environment. In most everyday situations, the …

New neurophysiological results show the existence of multiple transformations of color
signals in the primary visual cortex (V1) in macaque monkey. These different color …

Understanding the brain requires a kind of thinking outside the main tradition of natural
science: the biology has to be linked to something intangible, a private experience …

Our understanding of how we see color has benefited from the long tradition of visual
psychophysics. More recently, models and methods from psychophysics are guiding modern …

Highlights•Vertebrate colour vision started with 4 cone opsins and involved reductions.•
Pancrustacean colour vision went through multiple losses and duplications.•Colour …

Color processing begins with the absorption of light by cone photoreceptors, and progresses
through a series of hierarchical stages: Retinal signals carrying color information are …

Color vision is an illusion created by the interactions of billions of neurons in our brain.
There is no color in the external world; it is created by neural programs and projected onto …
