If you’ve ever seen a post or tree with a purple stripe painted on it but don’t know exactly what it meant, you should keep your distance. The color means means no trespassing.
“It holds the same weight and the same law violations apply. It’s no trespassing period,” Ashley Pellerin, an agent for the U.S. Department of Agriculture’s extension service in Prairie View, Texas, told KETK.
People might be able to tear down a sign easily, but it is much more difficult to get rid of purple paint on a tree or a post.
