A beam of white light is made up of all the colours in the spectrum. The range extends from red through to violet, with orange, yellow, green and blue in between. But there is one colour that is notable by its absence.

Pink (or magenta, to use its official name) simply isn’t there. But if pink isn’t in the light spectrum, how come we can see it?

Here’s an experiment you can try: stare at the pink circle below for about one minute, then look over at the blank white space next to the image. What do you see? You should see an afterimage. What colour is it?

You should have seen a green afterimage, but why is this significant?

Magenta Ain’t A Colour

Magenta is the evidence that the brain takes option b – it has apparently constructed a colour to bridge the gap between red and violet, because such a colour does not exist in the light spectrum. Magenta has no wavelength attributed to it, unlike all the other spectrum colours.

Magenta Ain’t A Colour

This is part of a phenomena called QualiaW.

But somehow, through a yet unexplained process, the spikes are transformed into the experience of color and shapes. What we call the mind is the place where the electric spikes are transformed into Qualia. There are many scientific theories that try to explain the mind but none have been proven by experiments. Scientists are still unable to comprehend the mind, measure it or even localize it in the brain. Yet the mind exists because we are aware of it every day.
