Skulls appear to be completely different colours thanks to optical illusion… when they are BOTH red
- Two skulls appear to be orange and purple, but they are actually both red
- The mind-bending optical illusion left some baffled after it was shared on Reddit
- However some believe it is not a true illusion as there are two shades of red
An optical illusion featuring two skulls that are seemingly different colours has sparked a debate online.
The image, posted on Reddit, appears to show an orange and a purple skull side-by-side.
But users were left shocked when it was revealed they are actually both red skulls.
The key to the illusion is the yellow and blue stripes that run through the shapes, tricking the mind into seeing different shades.
What colour do you see? An optical illusion featuring two skulls that appear purple and orange has sparked a debate online. The poster explained the two shapes are actually both red
However some questioned whether the illusion truly worked as they claimed the skulls are based on two different shades of red.
The illusion left users baffled, with one asking: ‘Can someone explain? I see purple and orange. I want to see the red ones I mean.’
Explaining how it works, one posted: ‘Look between the vertical line. On the left the red is coloured over the top the yellow lines with the blue lines uninterrupted.
‘On the right the red is coloured over the top the blue line with the yellow line uninterrupted.’
Debate: Some users were impressed by the illusion and asked for help understanding how it works. However others claimed it wasn’t a true illusion as the reds are two different shades
One user even went so far as to remove the yellow and blue out of the image to reveal the red skulls and point out that the reds of red are ‘not even close to the same’.
It comes after a teacher accidentally stumbled upon a mind-boggling optical illusion after drawing the outline of poppies for their students to cut out.
Posted on Reddit the Canadian user by the name of SlipperyPockets explained that they had made a stencil on a piece of red card, but when looking at the curved flower shapes they appear to overlap even though they’re all separate on the page.

It attracted thousands of comments and votes on the popular site with people complaining the illusion was hurting their eyes, and another saying it ‘made their brain tingle’.
The poppy illusion led some to debate over why it was baffling so many, agreeing it could be down to the gestalt continuity law.
‘Your brain is taking a shortcut and seeing the lines from one poppy continue a smooth, natural arc which is actually a line from an adjacent poppy,’ one explained.

The mind-boggling illusion left many saying it ‘hurt their eyes’ as they couldn’t figure out what they were looking at, some said they saw overlapping circles if they looked at the image for too long
Many Redditors claimed that the poppy illusion was something they’d never seen before: ‘This OP [original poster] might have legitimately stumbled on a brand new optical illusion.’
‘It’s been years since someone showed me a new optical illusion. Thank you!’
‘Yeah this is awesome stumbling upon a brand new illusion,’ added another.
