Colour vision articles from across Nature Portfolio

Whether end-spectral bias for red and blue in the visual cortex inherits from the pre-cortical stage or emerges within V1 remains incompletely understood. Here, the authors revealed a feedforward mechanism of end-spectral bias which is mainly transmitted through parvocellular pathway.

In this Stage 2 Registered Report, Blume et al. report results of a study on the contribution of colour vision mechanisms to circadian modulation by light.

How do you define colour? Nina Meinzer casts light on the vision it takes.

The diverse population of retinal cell types has now been shown to include one that does a neat trick: an interneuron inverts the sign of the retina's response to blue light, creating the blue-Off output signal to the brain.

A long-standing puzzle has been the seeming inconsistency between neuronal responses in primary visual cortex to colored stimuli and the elementary perceptual attributes of color vision. Nonlinear analysis resolves this paradox.

How do we tell red from green? Work on the primate retina shows how neural circuitry combines signals from individual cone photoreceptor cells to provide the basic building blocks for colour vision. See Article p.673
