Brazil's Flag: Green Field, Yellow Diamond, Blue Globe, 27 Stars

Design (adopted 1889, modified 1992):

• Green field: House of Braganza (Pedro I's dynasty) / forests.
• Yellow rhombus (lozenge): House of Habsburg (Maria Leopoldina) / mineral wealth.
• Blue celestial globe: Sky over Rio de Janeiro on Nov 15, 1889 (Republic proclamation), 8:30 AM.
• 27 white stars: 26 states + Federal District (Brasília), arranged as constellations (Southern Cross, Scorpius, Triangulum Australe, etc.).
• White band: Motto "Ordem e Progresso" (Order and Progress) — Positivist inspiration (Comte).

One of the world's most distinctive flags—astronomically accurate for a specific moment in history.
