Colour blindness in human?

Color blindness, also known as color vision deficiency, is a condition in which a person has difficulty distinguishing certain colors or perceiving them accurately. It is a genetic condition that affects the way the cones in the retina of the eye respond to different wavelengths of light. The most common type of color blindness is red-green color blindness, where individuals have difficulty differentiating between shades of red and green. This condition is more common in males than females, as the genes responsible for color vision are located on the X chromosome. There is no cure for color blindness, but certain assistive technologies and strategies can help individuals with color vision deficiency navigate their daily lives.
