The hoist-side stripe on Chad’s national flag is blue.
Chad’s flag is a vertical tricolor arranged from the hoist to the fly as blue, yellow, and red. The hoist is the side nearest the flagpole, so the blue stripe appears on the viewer’s left when the flag is displayed normally.
The flag was adopted on 6 November 1959 for the autonomous Republic of Chad and retained after independence in 1960. Its colors combine influences from the French tricolor with the Pan-African colors associated with Ethiopia.
Blue is often connected with the sky, hope, and Chad’s relatively well-watered south. Yellow represents the sun and the Sahara, while red is associated with progress, unity, and sacrifice. Chad’s flag is frequently confused with Romania’s because both use blue, yellow, and red vertical bands; Chad’s blue is generally a deeper indigo.
