Netherlands Flag:
The Netherlands flag was officially adopted on February 19, 1937. At one time this tricolor flag was orange, white and blue, as those were the livery colors of William of Orange, a Dutch prince. In the 17th century, red replaced the orange as a flag color, because the orange dye used on the flag was unstable, and turned red after exposure to the sun.

Netherlands Coat of Arms:
The royal coat of arms is placed on a mantle of ermine surmounted by a crown. The coat of arms date from 1815, when the Kingdom of the Netherlands was founded.
It is the same as the Dutch national coat of arms. It originates from the county of Nassau in Germany, and the central lion is the same as the lion on the oldest coat of arms of Nassau, dating from the 13th century.
