Recommendations for colored lights, 1967 and 1956

“Colored lights should be chosen using available data to have good recognizability and to cause the least amount of confusion. Table 6.5 recommends colors and describes their effect on color recognition of small-point light sources near the threshold of visibility (Dreyfuss, 1967). Table 6.6 shows 10 colored-light choices that were shown to reduce confusion error; that is, these 10 wavelengths had a less than 2% misidentification error in experimental studies (Chapanis and Halsey, 1956). Use of those values increases the number of color choices available to device designers that are more easily recognizable and can reduce misidentification.”
