Why Purple?
The color purple was chosen for a few reasons:
Visibility: It stands out in nature, unlike green, brown, or black.
Universality: Unlike red or orange, which often signal danger or construction, purple is distinct and less confusing.
Durability: Purple paint tends to withstand sun, rain, and weather better than printed signs.
How Landowners Use Purple Paint
To legally mark land with purple paint, landowners must follow specific guidelines:
Marks should be vertical lines at least 8 inches long and 1 inch wide.
They must be placed on trees or posts between 3–5 feet off the ground.
The markings should be spaced every 25–100 feet depending on visibility.
This ensures that anyone approaching the property will clearly recognize the warning.
What Happens If You Ignore It?
If you ignore a purple fence or marking and enter the land without permission, you can be charged with trespassing, which can result in:
Fines
