The Flag of Westarctica has gone through many changes since the nation first declared itself a sovereign territory. Although the original flag of the Achaean Territory was generally considered to be an eyesore, subsequent flags were designed to be more aesthetically pleasing while also encompassing the values of Westarctica. There have been five flags representing Westarctica since the nation was first founded. Only two of these flags have ever actually flown on a flagpole.
The specific tincture of blue is called "Westarctica Blue" and is considered a protected official color of Westarctica.
In 2016, the Grand Duke filed a copyright claim with the U.S. Copyright Office attempting to get the new flag design and color copyrighted, however his claim was denied due to their opinion that the design did not contain enough creative merit to qualify as a copyrightable work.
