# The flag of Czechia

**The flag of Czechia: A white band over a red band, with a blue triangle extending from the hoist to the centre.**

Ratio 2:3 · current design adopted 1920

*[Flag drawn on the page: Czechia]*

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.

| Poland | Poland is the same two bands without the blue triangle. |

## What the colours mean

*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.*
