The South African flag is the only national flag in the world with six colours in its primary design; green (37%), blue (18%), red (18%), black (10%), white (10%), gold (7%). What about other flags, what % of colours do they have?

If a class of 50 students wore colours to represent the South African Flag, 18-19 would have to wear green, nine would wear blue and nine red, five would wear black and five white and 3.5 would have to wear yellow (see below), but what about other flags? What percentage of students would have to wear what?
