Are You Color Blind? Take This Quiz to Find Out! (Animal Edition)

Test your vision in this color-blind test

Colour blindness is very common in society. According to the BBC, 1 in 12 men and 1 in 200 women suffer from color blindness in the UK. However, the word ‘blindness’ is a bit misleading. People with color blindness can still see color, but they see it differently to others. The cone cells in our eyes absorb blue, green, and red lights. If these cells are damaged in any way, it alters how we see colors. Many colors blend into one another rather than distinguishing from each other. In fact, it is extremely rare to find someone who only sees the world in black and white. Known as monochromacy or achromatopsia, this causes the person to see various shades of grey instead of color. Only 1 out of 33,000 people suffer from monochromacy in the UK.

History of color-blind tests:

One of the first recorded studies into color blindness was by physiologist Frithiof Holmgren in 1876. He compared the rise in railway crashes and incidents to the drivers not seeing the different colors in the signals. He created a test for color blindness. During a study, 266 employees of the Uppsala-Gávle railway line were asked to match up pieces of colored wools together. 13 of these employees were found to be color blind, and 3 could not see the color green. After this, he published the findings, and tests on employees became a regular occurrence in Sweden. Other countries soon implemented this too.
This discovery led to more tests being created. Japanese ophthalmologist Shinobu Ishihara created the most common test (the Ishihara test) in 1917. In this test, dots form an image with contemplating colors (red-green colors). Participants have to say what the image is. If someone has trouble seeing colors, they may not see an image on the plate.

Modern uses:

Nowadays, people can live with color blindness. However, it can be quite difficult in the school environment (which some subjects are heavily reliant on color) and some work occupations. Because of the variety of color blindness and different severities, several types of tests are used today. One is the Cambridge color test. This is a computer-generated test. Instead of a plate with a predetermined image embedded in it, this test will make a picture of a ‘C’ to appear on the background randomly. Participants then push a button to record when they saw said image.
Another is the Farnsworth Munsell 100 Hue Test. In this test, participants have blocks or pegs that are different shades of the same color. They are then asked to line them up in a certain order and sort them out. The US military uses a similar test to see if recruits can serve. If the recruits have a mild condition, they are still permitted to serve.
