4 is green in the USA, blue in Australia and New Zealand but black in the UK.
6 is Yellow in the USA but green in Australia and New Zealand.
Any suggestions on what this could be!
@sophocles,
I wonder if it has anything to do with national parks or landmarks
@sophocles,
There is a Green Mountain range in Vermont in the USA. In Australia and New Zealand there are Blue Mountains ranges. In the UK there is a Black Mountain range.
@cherrie,
Thanks for your suggestion but cannot find a connection. My initial thought was different colours used in some kind of sport but I am still struggling!
