Is it a beach or a door? Infuriating new optical illusion leaves the web baffled

The dress has gone down in recent history as one of the Internet’s most baffling optical illusions of all time.

However, a baffling new image is proving equally divisive as netizens try to figure out if they are looking at a beach or a door.

The photo was shared earlier this week on Twitter by social app 9GAG, who asked its followers to determine what they saw. 

The caption for the image read: ‘Is this a door, or a beach? Don’t let this become the next ‘Black and Blue Dress’ please.’ 

A new optical illusion is leaving the web baffled as netizens struggle to determine whether this is an image of a beach or a door

Looking at the photo vertically the image could easily be a section of a door, with the blue being the door itself while the turquoise acts as the frame and the cream as the concrete surround.

But flip the image horizontally and it resembles a stretch of beach complete with cream coloured sand, sea green waters and a crystal blue sky.

The tweet amassed over 3,000 likes, quickly dividing 9GAG’s followers, with them unable to agree on what is in the image.

Twitter users were left divided with many insisting the image was a close up of a door frame due to the 'shadows' seen in the image

Several greed that the image was indeed a close up of a door with one responding: ‘What kind of sane person would say it’s a beach?’

Agreeing another added: ‘This is a door because there are dark shadows (gaps) between the concrete and the frame.’

Meanwhile others were convinced that they were looking at a beach with one Twitter sharing a snap of the supposed ‘original’ image which appeared to show people on the beach.

Meanwhile others were of the believe that it was a photograph of a beach that had been flipped on the side

They wrote: ‘The image has been altered to remove the people who were bathing in the beach.’

However, some argued that the ‘original’ image shared had been doctored to add the beach goers.

So far the image is yet to be indentified as a beach or a door – so what do you see? 

This is just the latest in a long line of optical illusions to baffle the web.

In May a photograph of a sports shoe divided the internet with thousands of people saying they think it’s either grey and green or pink and white.

However, others suggested that there may be some trickery at play, with the colours deliberately changed to fire up a debate. 

The shot of the lace-up sneaker, which has a strip down one side has seen thousands of people commenting on it after it was posted by Australian music station 99.3 B-Rock FM.

The image re-surfaced after appearing late last year but is now foxing the internet all over again. 

Mint and grey? Or pink and white? Australian music channel 99.3 B-Rock FM posted this image to its Facebook page and thousands of people have now shared it...but some are suspicious that the colour levels have simply been changed to make a pink and white shoe appear different

The station published the image with the words: ‘IT’S HAPPENING AGAIN! What do you guys see?? Most of us see pink and white but some see grey and green…’  

On Facebook, Lisa Butler wrote: ‘Flipping hell. I commented ages ago; I saw grey and mint green, now I see pink and white.’   

@Bernade27300176 said different age groups saw different things in her house: ‘This is scary…me and my husband see a grey shoe with pale green laces. My kids see a pink shoe with white laces…spooky.’

The photo was originally posted last year by Nicole Coulthard to a Facebook group, she captioned the image. 

‘My friend has just sent me this asking what colour the shoe is, I would say pale pink and white, but she insists its pale blue and grey. What do you girls see? Please tell me pink and white!’

WHY DO WE SEE COLOURS DIFFERENTLY? 

Every single person is unique and as a result, our brains process information differently. Depending on how you interpret colours, one person might see it one way, while the very next person who looks at it might see it differently.

Light enters the eye and hits the retina, which is the light sensitive tissue at the back of the eye. 

The light is converted to an electrical signal which travels along the Optic Nerve to the Visual Cortex in the brain. The brain makes its own unique interpretation of this electrical signal.

It is not surprising that many respondents changed their mind when seeing the colour in contrast to the two blue shades, as we perceive an object’s colour based on a comparison to its surrounding shades, not on the actual colour itself.

Assessing colour vision is just one of the myriad of examinations that can be undertaken during a routine sight test. It’s possible for colour blindness to go undetected depending on severity – as it’s impossible to see the world through another person’s eyes.

Conditions such as protanomaly, deuteranomaly and tritanomaly can range from inconvenient to quite dangerous – often preventing those inflicted from pursuing certain careers. If you have any concerns about your colour perception, you should seek an appointment with a registered optometrist.

Keisha Maree thought it was a matter of light, saying: ‘Those are peachy pink and white sneakers – they look ‘grey/green’ as the photo looks like it was taken at night.’ 

Back in 2015, a now infamous ‘dress’ divided internet users, who simply could not agree over whether it was black and blue or gold and white – with even Kim Kardashian and Taylor Swift joining in on the debate.

One year later, the Adidas jacket did the same, with people saying that they saw numerous colour combinations, including blue and white, green and gold, black and brown, and green and brown.
