The black compass on the flag symbolizes the seafaring residents, and the red star represents the six original villages of Bonaire. The yellow signifies the sun, and the blue signifies the sea.

Actually, this emoji is the flag of Bonaire, not the entire Caribbean Netherlands. It was designated in Unicode to represent the three islands (Bonaire, Sint Eustatius, and Saba). When recommending diving spots or hidden gems in the Caribbean to a friend, using this emoji can make you seem like you're in the know.
