Color blindness is a condition that affects a person’s ability to perceive colors or distinguish between different shades. Some people mistakenly believe that color blindness means seeing only in black, white, and gray. While this is not entirely wrong, it is a rare and severe form of color blindness known as achromatopsia.

To simplify, a person with normal vision can see and differentiate between millions (perhaps even billions) of colors, whereas a colorblind individual can only perceive hundreds of thousands or fewer. Color blindness is not an illness—it is a genetic condition, meaning newborns can inherit it from one or both parents who have color blindness. It is advisable to test children for color blindness once they are old enough to recognize color differences but before they reach high school age. The most common and simplest method for testing is the Ishihara Test.

While color blindness may not seem like a significant issue, it can sometimes lead to life-threatening situations (no exaggeration!). In professions such as medicine, military, construction, and IT, color blindness is often a disqualifying factor. In graphic design, photography, videography, and other visual arts, it poses a serious challenge—but that doesn’t mean success is impossible!

Thankfully, modern technology provides tools that help colorblind individuals perceive colors more accurately. Devices like color oscilloscopes and spectral meters in cameras offer insight into color composition in photographs. Additionally, simple color-picker tools assist in identifying colors or selecting the best combinations for design work.

There are also physical tools to aid color perception, such as EnChroma glasses, which help certain types of colorblind individuals see a broader spectrum of colors.
