COLOR IN VISUAL SIGNALING

SELF-LUMINOUS AND NON-SELF-LUMINOUS VISUAL SIGNALS ARE DEFINED AND IT IS POINTED OUT THAT THE EYE IS NOT INFLUENCED MUCH BY EITHER BUT BY THEIR SURROUNDINGS, USUALLY A DARK SURROUNDING FOR THE FORMER AND A BRIGHT SURROUNDING FOR THE LATTER. THE FACTORS WHICH INFLUENCE SIGNAL DETECTION AND IDENTIFICATION ARE LISTED AND THE ROLE OF THE CHROMATIC ASPECT OF THE VISUAL SIGNAL IS DISCUSSED. TWO EXPERIMENTS ARE DESCRIBED, ONE ON VISIBILITY OF TARGET-SURROUND COLOR COMBINATIONS AND THE OTHER ON CONSPICUITY OF RED-GREEN AND VIOLET-GREEN YELLOW DIFFERENCES COMPARED TO LIGHT-DARK, AND SUGGESTIONS ARE MADE AS TO THE APPLICATION OF THESE RESULTS IN DETERMINING THE BEARING OF CHROMATIC DIFFERENCES ON THE VISIBILITY AND IDENTIFICATION OF SIGNALS.
