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. WebMay 21, 2024 · Results. The results of the Rayleigh test were similar to the values proposed in the anomaloscope user’s manual, however, with a small shift of R C and R 2 towards the red color. The double-peak distribution of R 2 with a small second peak (approximately at R 2 = 52) was mainly due to the measurements in male subjects (n male = 8, n female = 2), … how to style side swept bangs fine hair https://ateneagrupo.com
