Roughly 8% of the men and 0.5% of the women on the planet suffer from some form of colour blindness, a condition that limits their ability to perceive certain shades. For the majority, it’s the result of a genetic inheritance coming from their mother, but some people may become colour blind because of diabetes, MS, ageing, or substance abuse.
For everyone else, trying to imagine what it must be like to live in a colour-blind world can be difficult. Most colour blind people have vision as clear as everyone else, but they are unable to perceive red, green, or blue light. In some extremely rare cases they might not be able to see any colour at all.
For a simple measure, statistics reveal that most people with a moderate case of red/green colour blindness will only be able to correctly identify five colouring pencils from a box of 24.
A series of images produced by Swiss graphic designer Daniel Flück offer people without colour blindness the chance to get an idea of what those who do see, comparing three different types against a normal image.
People with Protanopia struggle with colours in the green, yellow and red spectrum. Those with Deuteranopia see even more pronounced problems in the same colour range, while those with Tritanopia can see red and green, but have problems with blue and yellow vision. In the gallery below, you can compare and contrast each of the three varieties against a normal image, and see the world like you have colour blindness.
