Italy

The Italian Tricolore is composed of three equal vertical bands of green (hoist), white (center), and red (fly), each occupying exactly one-third of the flag's width. The overall proportion is 2:3 — the same as the French Tricolore, which served as the direct inspiration for the Italian flag's structure. The three bands are perfectly rectangular with no additional emblems on the standard civil flag.

Like France, Italy has a separate state/war flag that bears additional symbols. The Italian presidential standard and certain state uses feature the Italian coat of arms — a white five-pointed star on a cogwheel, flanked by olive and oak branches — in the center. The colors are standardized to specific Pantone values: green to Pantone 17-0145 TPG and red to Pantone 18-1660 TPG. These are notably different from the Irish flag, which uses a lighter green.

The proportional similarity to the French Tricolore is not accidental. The Italian flag was directly modeled on the French design during Napoleon's campaigns in the Italian peninsula. The substitution of green for blue is the defining visual departure that makes the Italian flag distinct — and the source of considerable debate among vexillologists about exactly why green was chosen.

The Italian Tricolore has its origins in the revolutionary period of the late 18th century. The first recorded use of green, white, and red together appeared in 1794 in Bologna, when two students displayed a revolutionary cockade in those colors. The colors gained wider political traction in 1796 when the Cispadane Republic — a French client state in northern Italy — adopted a horizontal tricolor of green, white, and red as its banner. When Napoleon reorganized Italian territories into the Cisalpine Republic, the flag was rotated to vertical bands, directly mirroring the French Tricolore's structure.

Several theories explain the choice of green. The most widely cited is that green was the color of the uniforms of the Lombard Legion, the Italian volunteer militia that fought alongside Napoleon. Another theory credits the green to the meadows and hills of the Italian landscape, with white representing the snow of the Alps and red the blood shed for Italian liberty. Yet another interpretation traces the colors to the heraldic shields of Italian city-states — particularly Milan and Florence, both of which used green prominently.

The Tricolore was formally adopted by the Kingdom of Sardinia under King Charles Albert in 1848, during the first wars of Italian independence. The Savoy dynastic shield (a white cross on red) was placed in the center during the Kingdom of Italy period (1861–1946). After the abolition of the monarchy by referendum in 1946 and the proclamation of the Italian Republic, the dynastic emblem was removed and the current plain tricolor was adopted with the Constitution of 1948.

Today, the Tricolore is deeply embedded in Italian cultural identity. The colors appear everywhere from sports uniforms (the national football team's azure blue jerseys being a separate heraldic tradition) to food packaging. The phrase "verde, bianco e rosso" (green, white, and red) is shorthand for Italian identity. The flag's birthday, January 7th, commemorates the date in 1797 when the Cispadane Republic officially adopted the tricolor.
