Have you ever taken one of those color vision tests? They’re used to determine if you have color vision deficiency, a condition that’s usually inherited. If you have poor color vision, your ability to see the difference between certain colors is lessened.

People with color vision deficiency do not always know they have it! Usually, people find out in real-life situations such as pulling up to traffic lights and not knowing exactly what colors are showing. Most commonly, people affected by color vision deficiency see:

  • Different shades of red and green
  • Different shades of blue and yellow

Although many people equate color vision deficiency with color blindness, true color blindness actually describes someone who only sees in shades of black and white which is rare. But here’s a quick to help determine whether you have a color vision deficiency or not.

4 Kinds of Color Blindness

Color blindness – or color vision deficiency (CVD) – affects approximately 8% of men and 0.5% of women.[1] Broadly, there are four kinds of color blindness (it’s not just seeing in shades of grey) and we have some pictures to show you what each looks like.

Total Color Blindness

We’ll cover this one first because while it exists, it only occurs in 0.00003% of the world’s population.[2]

Deuteranomalia

About 4.63% of men unknowingly suffer from this form of color blindness, making it the most common form. Colors, especially reds and greens, will seem faded or lack their natural brightness.

Protanopia

1% of men have this less common form of color blindness. There seems to be a greater contract in Protanopia because while all reds and greens will lack brightness, other colors such as yellows and blues tend to stay the same.

Tritanopia

This form of color blindness affects both men and women equally, but rarely and at very minimal levels. People will this CVD perceive the world in tones of pink and green.
