In some U.S. states, if you’re hiking around outside, you might stumble across a fence painted purple.
It’s not for decoration, there’s an actual meaning behind it. It means “No Trespassing” on remote and private properties in several states.
“It holds the same weight and the same law violations apply,” Prairie View A&M Extension Agent Ashley Pellerin told MyEastTex.com. “It’s no trespassing period.”
The concept of purple fences started in Arkansas in 1989 as a way for property owners to warn the public of private land. The state of Texas adopted a similar law in 1997.
“The reason the Texas legislature did that is they were trying to keep landowners from constantly having to replace signs,” Jonathan Kennedy, the owner of EastTexasLands.com, told the website. “In Texas as we know, people like to take target practice at signs so they are having to replace them frequently.”
Pellerin said she believes the color purple was used because people who are colorblind can still see it.
“These marks, when placed properly, are assumed to be ‘posted—no trespass signs,'” says the Forest Resources Institute. It adds, “The use of written posted signs is still recommended at access points, such as gates. Unlike signs, marks are not easily removed or torn down and do not have to be replaced often.”
Some property owners apply the purple paint to trees if there isn’t a fence around. It works “just as a green light means go and a red light means stop,” according to the University of Missouri.
The law also went into effect later in Illinois, which lawmakers hoped would deter deer hunters from hunting.
“Most hunters are very respectful,” Illinois Forestry Association Secretary Dave Gillespie was quoted by the Chicago Tribune as saying. “But there are always bad guys who aren’t and ruin it for the rest of us.”

Other states where it might apply are Missouri, Maine, Arkansas, Florida, Idaho, Kansas, Montana, Arizona, and North Carolina, according to GeoCachingAustin.com. The law stipulates that vertical purple markings have to be clearly visible and need to be 8 inches long by 1 inch wide.
“Of course, not all land owners apply the paint the same. I run across the purple paint all over Texas, both on pine trees in the east and on fence posts in Central and west,” wrote the owner of the GeoCachingAustin website.
So, the next time you’re out hiking around, biking, camping, hunting, fishing, or hunting edible mushrooms, make sure to be on the lookout for purple.
