Question

why doctor is used green suit in operation theatre

Answer 1

1st resion:-




look at the blue or green color can refresh doctors vision from the red things, such as organs and blood of patients during surgery.

2nd resion:-

because the doctors vision continuously focused on the red colored patient's organ, where the red color can cause green colored optical illusion on the white colored surface and certainly can be annoying.

Answer 2

Red-green colour lie on opposite side of the colour wheel. That means  there is no such colour as reddish-green or greenish-red, unlike a bluish-green colour (according toOpponent Process Theory of Colour Vision). The brain interprets colours relative to each other, so the contrast between red and green makes it easier to look out for blood oozing out during a surgery. Also continuously looking at red desensitises the cones in the eye (cells responsible for colour vision), so looking at green scrubs during the surgery preserves the sensitivity of the eye to red.
