The colors of the Italian flag are green, white, and red. The flag is a vertical tricolor with green on the hoist side, followed by white and red. Green symbolizes hope, white represents faith, and red stands for charity, reflecting the nation's ideals and values. The flag has undergone various changes since its first adoption in the 18th century but has remained a powerful national symbol of unity and identity for Italy. The current version was officially adopted in 1946 after Italy became a republic.
