Optical illusion of strawberries leaves internet stumped as creator reveals they AREN’T red
The baffling brain teaser was uploaded to Twitter, with the creator saying the colours aren't what they appear
FIRST ‘that dress’ divided the internet when people argued over its actual colour – and now a plate of strawberries is causing mass confusion.
An image shared to Twitter shows what appears to be a selection of red strawberries on a tart filtered with a blue hue, but all is not as it seems.
In actual fact, there is not a single red pixel in the image.
The confusing illusion was uploaded by Japanese Professor of Psychology, , who specialises in creating optical illusions and regularly uploads them on Twitter.
Akiyoshi explained: “Illusion of strawberry by the two-color method. Although this image are [sic] all made of the pixels of the cyan (blue-green), strawberries appear red.
“Strawberries appear to be reddish, though the pixels are not.”
So why can we can see red?
Unlike the dress image, everyone is seeing the same thing this time, but the illusion is created through a phenomenon called colour constancy.
Bevil Conway, an expert on visual perception from the National Eye Institute, explained that your brain simply “colour corrects” when visuals are processed in a different light.

Bevil said to : “If you imagine walking around outside under a blue sky, that blueness is, in some sense, color-contaminating everything you see.
"If you take a red apple outside under a blue sky, there are more blue wavelengths entering your eye.
"If you take the apple inside under a fluorescent or incandescent light without that same bias, the pigments in the apple are exactly the same but because the spectral content of the light source is different, the spectrum entering your eye that's reflected off the object is different."
Many Twitter users have debated about the actual colours of the strawberries, with some isolating the fruit and putting it on a white background.
They claim only blue and grey colours are seen when this happens.
