The symbolic interpretation of the flag's colors represents the three cardinal virtues:
Green = Hope
White = Faith
Red = Charity
green--hope
white--faith
red--charity
Green is for the land of Italy. White is for the Alps of Italy. Red is for the blood spilled on Italian soil.
The colours have been chosen to represent the Cispadane Republic (an alliance of northern Italian provinces) as early as January 7, 1797. However, its current form has been in use as the Italian flag since January 1, 1948.
The Italian flag is red, white and green.
There exist no consensus on the meaning of colors on the flag.
