Ever had an argument with someone over whether that red jacket is actually blue? You wouldn’t be the first person, with one in every 200 women on Earth officially colourblind. Thing is, many of us don’t even realise we have the condition. We just blissfully go through life thinking colours are meant to be seen that way.

Colour blindness, a hereditary disease, comes in many different forms. You can either have a hard time differentiating between shades of red, green, blue or yellow (or not see them at all) or simply view the world in the black and white – although this is very rare.

Now a website, can show you exactly what being colourbind is like. You simply upload a photo and then select how the different types of colour blindness would affect how you view particular scene. We put it to the test and the results were very interesting to say the least.

For example, those who cannot see green (a condition known as Deuteranopia) would see the world like this:

^ Not-so vivid anymore.

Whereas people whose eyes have trouble seeing blue (known as Tritanomaly) properly, but are not completely blind to it, would see the same scene like this:

And those who cannot see red (known as Protanopia) at all would see it this way:

Here’s how people with these types of colour blindness would see a rainbow umbrella.

Although this website is fun to play around with, there are a number of tests used by professionals to determine whether someone is medically colourblind, one of the more common ones being the Ishihara plate test. Take it below and see how you go – you might just find you’ve actually been seeing the world through rose-coloured (or blue-coloured, or green-coloured) glasses this whole time.
