WebThe Rayleigh match ( Rayleigh, 1881) is a traditional tool for classifying color vision. Typically, an observer is shown a circular, bipartite field of less than 2-deg diameter. One half-field contains a near-monochromatic yellow light ( ca. 590 nm), while the other contains a mixture of red ( ca. 679 nm) and green ( ca. 545 nm) light.
