New netherlands flag

You're referring to the flag of New Netherland, which is a historical colony that existed from 1624 to 1664. The flag of New Netherland was the same as the flag of the Dutch Republic, which was a horizontal tricolor of orange, white, and blue.

Here's a brief history of the flag:

• The Dutch Republic, which was a confederation of seven provinces in the Netherlands, had a flag that consisted of three horizontal stripes: orange, white, and blue. The colors were said to represent the three main principles of the Dutch Republic: orange for the House of Orange, the royal family; white for the country's neutrality; and blue for the sky and the sea.
• When the Dutch West India Company established the colony of New Netherland in 1624, it used the same flag as the Dutch Republic. The flag was flown over the colony's settlements, including New Amsterdam (now New York City), which was the capital of New Netherland.
• In 1664, the English took control of New Netherland from the Dutch, and the colony became part of the British Empire. The English replaced the Dutch flag with the British flag, which is still used today.

Here's a picture of the flag of New Netherland:
