Here we have a good-looking guide that we found in the vexillology category of Reddit from a couple of years ago that shows a selection of flags from around the world that feature the colours purple and yellow. Check out this design to learn about flags with the colours purple and yellow which together signify authority, power, and high-contrast boldness along with the places they came from.

And here we have some larger pictures of the purple and yellow flags in the guide for you to see as well as a little bit of information about the flags themselves or if not the places they came from courtesy of Wikipedia with links to where you can get more.
