Design and Layout of the Cuba Flag
Legal specifications established by President Tomás Estrada Palma on April 21, 1906, and reinforced by Law 42 in 1983, define the design and layout of the flags from Cuba using geometric and color parameters. The table summarizes key technical specifications of Cuba’s flag from regional and international sources.

| Orientation | Hoist vertical, fly horizontal |
| Colors | Blue stripes, white stripes, red triangle, and a white star |
| Digital colors | Blue: RGB(0,42,143), HEX #002A8F Red: RGB(207,20,43), HEX #CF142B White: RGB(255,255,255), HEX #FFFFFF |
| Print colors | Blue: CMYK (100, 71, 0, 44) Red: CMYK(0, 90, 79, 19) White: CMYK(0,0,0,0) |

If we analyze the history of Cuba flag, in some past documents, it used to have a red equilateral triangle, each side matching exactly in length. Its base runs flush with the hoist edge, aligned without deviation. Spaced evenly across the design, a white five-pointed star holds position; its uppermost tip faces the fly end of the banner. Symmetry guides the placement, ensuring balance through careful angular distribution.
Flag of Cuba: Meaning and Symbolism
Academic and official Cuban sources offer varied interpretations of the colors and design of the Cuban flag, with meanings that have evolved through different historical periods and government statements. Most reference materials agree that the three blue stripes stand for the island’s three original military or territorial divisions under Spanish rule: Western, Central, and Eastern Cuba.
In Cuba's flag, the two white stripes are widely considered symbols of the purity and strength behind the independence movement, though some accounts instead link them to ideals such as justice or peace.
The red equilateral triangle is widely attributed dual symbolic meanings in vexillological literature. So, the Cuba flag meaning primary interpretations link the red color to the blood sacrificed by Cuban patriots during independence struggles against Spanish colonial rule.
Scholars note that the triangle on the Cuban flag draws from Masonic symbolism, representing the values of equality, liberty, and fraternity, principles central to many revolutionary movements across former Spanish colonies.
What Cuba’s flag? Represents:
The three blue stripes often represent Cuba’s original three military districts or provinces.
The two white stripes commonly symbolize purity, integrity, and commitment to independence.
The red equilateral triangle reflects sacrifice in liberation struggles and is sometimes linked to Masonic ideals of equality, liberty, and fraternity.
The white five-pointed star (La Estrella Solitaria) stands for independence and national unity.
Overall, the flag’s colors and layout express pride, resilience, and shared identity.
How to Identify the Flag of Cuba?
Across the Caribbean, the Cuba flag is commonly displayed at international border checkpoints, airport immigration halls, and port terminals where Cuba is. They are often positioned alongside other national flags near country signage, passport control counters, and customs areas. It also appears on public transit maps, tourism kiosks, and online booking platforms, where it serves as a recognizable marker for Cuba-related travel services and destinations.
Ways to recognize the Cuban flag:
Look for five horizontal stripes in a blue-white-blue-white-blue pattern, running cleanly from top to bottom.
Confirm a red equilateral triangle on the hoist side, extending roughly one-third of the flag’s length.
Locate a single white five-pointed star centered inside the triangle, with one point facing toward the fly edge.
Distinguish the Cuban flag colors from similar Caribbean flags by checking for three blue stripes, two white stripes, and the exact red triangle placement.
Notice the dark, saturated blue shade (azul turquí), which appears deeper than the lighter blues used on other national flags.
Verify there are no added emblems, coats of arms, seals, or text beyond the lone white star.

History of the Flag of Cuba
The Cuban flag was first introduced in 1849 by Venezuelan-born general Narciso López and Cuban poet Miguel Teurbe Tolón, who designed it while living in exile in New York City.
Miguel’s wife, Emilia Teurbe Tolón, sewed the first flag following their specifications. Created as a rallying symbol for Cuba’s independence from Spanish colonial rule, the design also reflected the hopes of some exile groups at the time who envisioned possible annexation to the United States.
The short history of the Cuban flag:
1850: The flag was first raised publicly on May 19 in Cárdenas during one of Narciso López's military expeditions aimed at liberating Cuba from Spanish control.
1851: López carried the flag in subsequent battles at Playitas, though these military efforts were ultimately unsuccessful in achieving immediate independence.
1868: The Cuban War of Independence began, and the flag designed by López and Tolón gained recognition as a revolutionary emblem uniting independence fighters.
1899-1902: Following the Spanish-American War, the United States flag flew over Cuba as US forces administered the territory after Spain's defeat.
May 20, 1902: Cuba achieved independence, and Generalissimo Máximo Gómez officially hoisted the Cuban flag at the Tres Reyes del Morro fortress in Havana, marking the flag's formal adoption as the national symbol.
April 21, 1906: President Tomás Estrada Palma issued a decree establishing formal design specifications, including the azul turquí blue shade and precise geometric proportions.
1959: The Cuban Revolution, led by Fidel Castro, established a new government structure, yet the flag's design remained unchanged, maintaining continuity with pre-revolutionary national symbols.
1983: The National Assembly of the People's Power issued Law 42 on National Symbols, codifying flag display protocols and usage regulations.
