About colourblindness:
About 1 in 12 men (8%) and 1 in 200 women in the world are colourblind, though not all the cases are extreme, and someone might not even realise they have partial colourblindness. Colour blindness is usually from a genetic cause (in your DNA and inherited from parents). The most common kind is red/green colourblindness, and is partial or complete loss of sensitivity to red and green colours. In the more extreme cases (protanopia - loss of red, and deuteranopia - loss of green) colours containing red or green appear yellow or brown, and blues and purples are confused. Less extreme cases (deuteranomaly - partial loss of green) are most common, where reds appear browner and purples appear bluer. https://en.wikipedia.org/wiki/Color_blindness#/media/File:Color_blindneā€¦
