The S-opponent pathway has a reputation for being sluggish relative to the L/M-opponent pathway. Cottaris and De Valois [Nature 395 (1998) 896] claim that S-opponent signals are available in Macaque V1 only after 96-135 ms whereas L/M-opponent signal...

By determining the locations of boundaries between colour categories, we measured changes in the colour appearance of test-reflectances as a function of the simulated illumination. Test-reflectances were displayed against a variegated background of r... Read More about Colour constancy in context: Roles for local adaptation and levels of reference.
