It's almost the end of the week, we're in what feels like the 17th months of lockdown, and the brain cells may be feeling frazzled but, if you can - try and fire them up to figure this out.
Once again, people on the internet are divided.
They've been left scratching their heads and debating a mind-bending picture filled with a spectrum of colour.
The question on people's lips is: "How many colours do you see?"
Answers range from 11, to 3 and a whopping 39 - so there really is a range of possibilities.
At first glance, the image, shared to Twitter, looks like it will be simple to figure it.
The original poster asked: "How many colors do you see???? i see 3."
People are finding it difficult to agree on the exact number of colours they can see.
In addition, visibility depends on a screen's level of brightness, saturation and contrast.
One person joked: "I see 103."
Another said: "I see 11 distinctive colors and more if you count faint lines between two of the colors as they transition."
A third added: "20 -21, if the thin lines are included."
One person had a decent explanation as to why people had such varying answers.
They tweeted: "To all the people here being confused.. it mostly has something to do with your output device (smartphone, laptop etc.), bc the color rendering differs a lot more between devices than you think!
"Also if you are viewing it in dark or light mode, your surrounding light in real life, etc."
