The pupil is the opening in the center of the iris where light enters the lens, which then focuses it on the retina. No matter what colour eyes we have, everyone has black pupils. The pupil is black because all the light that enters through the pupil is absorbed inside the eye and none of it is reflected.Imagine the pupil to be coloured, let’s say red. White light (sunlight, incandescent light, fluorescent light) consists of the seven ROY G BIV colours: red, orange, yellow, green, blue, indigo, and violet. The red pupil would reflect the red portion of light, which would not enter the eye. This would distort the colour of everything we see. It would be like perpetually looking at the world through stained-glass windows. So, as it turns out, the colour of the pupil must be black in order for us to see the spectrum of colours from red to violet.
