The Flag of Ireland has three equal vertical bands of green (hoist side), white, and orange. This tricolor is also the symbol of the Irish nation in other countries, most notably in Northern Ireland among the Irish national minority. There are three colors in the Irish flag.
Green, white, and orange. All the colors on the flag stand for something. The green stands for the Roman Catholics in Ireland, the orange represents the Northern Irish Protestants, and the white stands for the aspiration of peace between Them.
