Tricolor flags: what do they mean?

Question

Lots of countries have tricolor flags. Presumably all the colours mean something. Does anybody know what they all are? Where the same colour appears in two different flags, does it tend to mean the same thing?

Answer 1

it simply means green (being the Irish) and the orange (being the English or protestant orangemen) and the white meaning peace and that means that the flag was built to mean peace between the English and Irish... but the English continued the pillage rape and steal all our spuds and cause 2million people to leave their homeland for food and a better life due to a famine..
