Should I add this documentation in 02_minimal_measures document?

Color blindness, also known as color vision deficiency (CVD), is an eye condition that makes it difficult to see colors or differentiate between them. The severity of color blindness can range from mild to severe.
Causes
Color blindness is usually genetic and inherited from a parent.
It can also be caused by other diseases, such as diabetes or multiple sclerosis.
Aging and taking certain medications can also cause color blindness.
Types
Red-green color vision deficiency
The most common type of color blindness, making it difficult to distinguish between red and green.
Blue-yellow color vision deficiency
A less common type of color blindness, making it difficult to distinguish between blue and yellow, or red and green.
Symptoms
Difficulty identifying colors
Seeing colors differently than others
Decreased attention span when coloring
Coloring with the wrong colors
Headaches or eye aches when looking at red on green or green on red backgrounds
Treatment
There is no cure for color blindness that runs in families.
Special glasses and contact lenses can help people see differences between colors.
An ophthalmologist can treat acquired forms of color blindness.
Impact
Most people with color blindness don't have problems with everyday activities

lets understand what is color blindness- color blindness also called as color vision deficiency (CVD), is a condition where individuals have difficulty distinguishing between certain colors. well in simple terms our eyes detects or understand colors with the help photoreceptor cells (cones) in the retina and when they don't function properly or are absent color blindness occurs . color blindness is not a common topic of discussion as according to a survey many people in the later stages of life realize they are color blind.
types-
The most common type is red-green color blindness, followed by the rarer blue-yellow deficiency and the extremely rare total color blindness (achromatopsia).
causes-
It is primarily genetic but can also result from eye diseases, nerve damage, aging, or medications.
symptoms-
The symptoms of color blindness vary depending on the type and severity of the condition. People with red-green color blindness may have difficulty distinguishing between shades of red and green, often confusing them or seeing them as the same color. Those with blue-yellow color blindness struggle to differentiate between blue and yellow hues. In severe cases, such as total color blindness (achromatopsia), individuals see the world in grayscale, with no perception of color at all. Some common signs include trouble identifying colors in traffic lights, difficulty matching clothing colors, and reliance on brightness or texture rather than color to differentiate objects. In milder cases, individuals may not even realize they are color-blind until tested. The condition does not typically affect visual clarity but can impact daily activities, especially in professions or tasks where color differentiation is essential.
how to be inclusive-
To promote inclusivity, designs should use high contrast, color-blind-friendly palettes, and alternative indicators like patterns, textures, and text labels rather than relying solely on color. Digital platforms should adhere to WCAG guidelines, incorporate color-blind modes, and offer customizable settings. In workplaces and education, presentations, charts, and materials should avoid color-dependent information, ensuring accessibility through symbols and labels. Early screening, awareness, and the use of color simulation tools can further support inclusivity, creating an environment where color-blind individuals can engage fully without barriers.
