A: In order to avoid collision, in theory, the color difference between the two should be 22.5 degrees, but the practice proved that the four angles of 15 degrees, 45 degrees, 75 degrees and 90 degrees works well, the yellow version of the visual stimulation Weak, poor visual sensitivity, it is generally set to 90 degrees, the most sensitive to the 45-degree angle of vision, the original main color of the original magenta or cyan is fixed at 45 degrees. For example, for the blue sky and white clouds, the cyan version should be set at 45 degrees. For the sunset and setting sun, the magenta version should be set to 45 degrees, and the magenta and blue ones should be set to a non-45 degree angle. For 15 degrees, the black version is set to 75 degrees.
