How is the trichromatic cone mosaic of Old World primates sampled by retinal circuits to create wavelength opponency? Red-green (L versus M cone) opponency appears to be mediated largely by the segregation of L versus M cone signals to the centre versus the surround of the midget ganglion cell receptive field, implying a complex cone type-specific wiring, the basis of which remains mysterious. Blue-yellow (S versus L+M cone) opponency is mediated by a growing family of low-density ganglion types that receive either excitatory or inhibitory input from S cones. Thus, the retinal circuits that underlie colour signalling in primates may be both more complex and more diverse then previously appreciated.
