Daytime colour preference in Drosophila depends on the circadian clock and TRP channels
Innate colour preference in adult fruit flies changes with the time of day, and depends on rhodopsins 1 and 7, TRP channels and the circadian clock.

A neuronal circuit for colour vision based on rod–cone opponency
Colour vision is thought to rely on the comparison of signals from cone cells in the retina, this paper identifies a class of mouse retinal ganglion cells (J-RGC) that integrates an OFF signal from ultraviolet-sensitive cones with an ON signal from green-sensitive rods, producing a colour-opponent channel that may enable animals to detect urine territory marks; the underlying circuit may also explain why humans experience a blue shift in night-time vision.

Neurons show their true colours
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
