Got my blue jeans on and my blue Harley shirt for St. Patrick's day.
Blue:
Americans usually wear green on St. Patrick's Day -- but in Ireland, green was considered to be an unlucky color for a long time. Green was considered the favorite color for the Good People, or faeries, in Irish folklore, and they liked to steal people and especially children who wore too much green.
The original color associated with St. Patrick was blue, not green.
Blue Two:
According to Faith Central, Blue not green is the color originally associated with St Patrick. "St Patrick's Blue" is used on Ireland's Presidential Standard or flag, while the Irish Guards sport a plume of St Patrick's blue in their bearskins. The emphasis on green is thought to be linked to "wearing the Green", a symbol from the 18th century on, of sympathy with Irish independence.
