Kate Garraway has caused her followers to look twice after she shared a baffling optical illusion.
The 52-year-old Good Morning Britain presenter shared an image on Instagram that has caused huge debate among her followers, who tried to get their heads around the bizarre illusion.
The I’m A Celebrity star posted the image, which contained two blocks that appear to be totally different shades of grey piled on top of one another.
There is some debate as to whether the two blocks are a different colour or the same but if you put a finger between the blocks, it becomes clear that they are exactly the same colour, much to the confusion of your eyes.

The image is made to look different due to the effect which has darker and lighter shading running through the middle.
Kate captioned the image with: “This caused a right stir in our house tonight…”
It went on to cause a right stir among her 588,000 followers, with more than 20,000 liking the image and hundreds taking to the comments to add their two-penneth.

Her fans were as impressed by the illusion as they were baffled, with one commenting: “That’s mad! You’d swear they were totally different colours.”
Anther wrote: “Oh my gosh, that’s incredible. They eye can play such tricks on you.”
A third added: “This is unbelievable.”
The image is called the Cornsweet illusion and was first used by Tom Cornsweet, who was an experimental psychologist in the 1960s.
The image shared by the Smooth Radio host is called the Cornsweet illusion and was first documented by experimental psychologist Tom Cornsweet in the 1960s.
He worked with visual perception and was among the first to note that colour is perceived differently along with the shading of 3D images.

It all depends on how they are lit and where the shadows fall.
In the image it looks like the upper square is darker and the lower one is lighter as that is what our brain thinks is a logical response to the image.
The illusion is created by the light falling from the upper left and the two blocks being tilted away from us.
This way, we see the upper block as lit up which the lower block is in shadow.
When the two contrasting shadings are combined between the two blocks, it makes our brain interpret the top block as dark and the bottom one as light.
