Which other two countries have flags with the same colours as Colombia?

A flag of unequal yellow, blue, and red horizontal stripes was adopted by the new country of Gran Colombia in 1822. Although that country dissolved in 1830, the succeeding states of Colombia, Ecuador, and Venezuela incorporated that flag’s tricolor design into their respective flags. Those of Colombia and Ecuador retain the larger yellow stripe, while that of Venezuela has stripes of equal size. The Venezuelan flag is also distinguished by an arc of stars in its center and by the national coat of arms in the upper hoist corner. The Ecuadorian flag also depicts the country’s coat of arms, though in its center.
