Neuroscientist's mindblowing test goes viral with people divided over what colour they see

A new experiment about colour has sparked conversation online and people can't seem to agree.

Don't pinch yourself, it's not 2015 again and it's not about whether a dress is blue or black, or white and gold - but it is related to colour perception.

The easily accessible online test looks at your ability to determine colour, with a formula cooked up by some neuroscientists that want to prove that everyone sees things differently.

This viral test can be found on the website ismy.blue, where you can find out where you place on the colour perception conundrum between two simple colours - blue and green.

In the 'About' section, they explain: "People have different names for the colours they see. Language can affect how we memorise and name colours. This is a colour naming test designed to measure your personal blue-green boundary."

During the test, a number of screens pop up displaying different shades of green or blue, and it is up to you to decide which category it falls into, with colours getting more similar as time goes on.

It only takes a few seconds, with certain colours looking only slightly different in shade each time, as it will become harder to make a decision.

Well it was for me, at least.

At the end, it shows you a gradient chart, which determines how you recognise colour compared to the rest of the world's population.

Using previous results to chart you along their gradient, the results are put into a wider block, going from cleat green to a dark blue, and shows you exactly which point your brain switches from green to blue, as a hue line is put on the chart more to one side, highlighting where you sit.

This also compares you to the average person and reveals if you see turquoise as more of a blue or green colour.

The bizarre test went live in August this year, with the average hue score sitting around 175, though it should be noted that this can change depending on the influx of new results.

Patrick Mineault is a neuroscience and AI researcher, as well as the site's creator, detailing that you can be limited 'by the calibration of your monitor, ambient lighting, and filters such as night mode.'

So, you might want to turn turn them off if possible. He does also explained that it is 'for entertainment purposes only.'

Explaining that scientists and graphic designers use different methods to determine colour, before highlighting: "Here we use your monitor or phone to test how you categorise colours, which is far from perfect, since your calibration may differ from mine."

He continued: "Despite these limitations, the results should have good test-retest reliability on the same device, in the same ambient light, which you can verify by taking the test multiple times.

"If you want to compare your results with friends, use the same device in the same ambient light."

By using a specific formula to form a sigmoid curve, your responses are placed on it, as it is a 'logistic regression model'.

If you want to see where you place, why not give it a go.
