- Many World Cup viewers can’t tell teams apart due to color blindness.
- Color-blindness is a maternally-inherited condition (sometimes due to diabetes) whereby a fault eye nerve cell (“cone”) blocks color(s).
- A normal eye contains three separate cones that absorb red, green and blue light to see colors.
- Color-blindness means one cone is faulty.
- 320 million people worldwide are color blind (1/12 men, 1/200 women).
- Colour Blind Awareness has lobbied FIFA to take color-blindness into match day outfit considerations.
