The white-over-red bicolour alone is Poland's flag, which is exactly why the blue wedge was added in 1920. When Czechoslovakia split on 1 January 1993, the constitutional act said neither successor state would use the federal symbols; the Czech Republic adopted the flag anyway three weeks later, and Slovakia protested. The blue triangle reaches precisely to the midpoint of the flag's length. Czechia is one of the few countries that inherited its predecessor state's flag unchanged after a dissolution.

What the colours mean

  • White #FFFFFF From the Bohemian lion on red; the upper band
  • Red #D7141A The Bohemian field
  • Blue #11457E Added for Moravia and Slovakia, and to distinguish the flag from Poland's

Flag laws usually specify a Pantone chip, a CMYK mix or just a colour name. Converting any of those to sRGB is lossy, which is why published hex values disagree.
