The flag of Gran Colombia was based on Francisco de Miranda's Venezuelan tricolour which served as the national flag of the First Republic of Venezuela. It also served as the basis for the current flags of Colombia, Ecuador, and Venezuela, which emerged as independent nations at the breakup of Gran Colombia in 1831.
