Optical illusions, also called visual illusion involves the arrangement of images where the effect of colours or the effect of light sources or other variables leads to a wide range of visual deceptions. This phenomenon of optical illusion is not only fun to explore but also give insights into the functioning of your brain.
Thus, through this visual arrangement recently the internet witnessed a never seen colour before known as “true cyan”, which looked like a dazzling green-blue pigment. This colour was apparently only represented through the magic of optical illusion as it was difficult to capture it on a television screen, and was often diluted into a lesser form.
What does this optical illusion show?
On TikTok, a user named Kate Bacon posted a video that claimed to show people a colour they have never seen before. Her video acquired more than 21 million views on Tiktok.
She said, "It’s called true cyan, and most TVs and monitors aren’t capable of producing this pigment."
Thus, viewers are shown a red circle with a white dot against a blue background. Kate instructs that for a duration of at least 30 seconds, you need to stare at the white dot. She also said the longer you close your eyes better is the effect. Post this exercise, if you close your eyes really tightly, you should ideally see a ‘glowing orb’ in the colour of true cyan.
Post the popularity of the video, Bacon further explained other optical illusions including the Munker-White illusion.
Posted back in 2011, a similar video on YouTube instructs the viewer to gaze at the white dot in the exact middle of the red circle as the camera slowly pans out. Thus, after the video ends, the spectator will be able to see the true cyan colour display like a halo around the red circle. This video gained more than 177,000 views.
Several users in the YouTube video comments talked about they witnessed the colour. One user said that there is a cyan circle that follows their eyes everywhere they go, while one user said how the true cyan has turned out to be their absolute favourite colour. One user mentioned a hack about how if viewers blur their eyes midway, they can see the outline of the circle as half-bright blue and half bright red.
On Reddit, this optical illusion had gone viral with some different instructions.
"Stare at the red dot in the centre of the red circle. The longer, the better (two minutes and you’ll get a much stronger effect)," it explained. "Soon after staring, you’ll start to see a thin rim of light around the edge. Wait another minute keeping your head perfectly still. Slowly move your head backwards, making sure to keep your eyes focused on the dot at all times. The circle’s rim will glow brilliantly with true cyan!"
