If you look at the colour red for a long time and then look around you see things in greenish tinge. This is because the red cones in the eye get saturated and they take some time to recover. Since green is the complementary colour to red, we see green on white surfaces. During an operation, doctors and nurses continuously see red blood. This deep focus on red can lead to distracting green illusions on white surfaces. These green images could appear if a doctor shifts his gaze from reddish body tissue to something white, like a surgeon’s outfit. Thus, wearing green gowns makes the operation easier on a surgeon’s eyes.
A green illusion of the patient’s red insides may appear on the white background. (You can try out this “after effect” illusion yourself.) The distracting image would follow the surgeon’s gaze wherever he looks, similar to the floating spots we see after a camera flash.
