Do You Know Why Purple Paint is Used on Posts and Trees?

10 different states in the U.S., including the great state of Texas, use the color purple as a warning to trespassers.

Purple shows well in the outdoors. In fact, it’s one of the only colors that color blind people can easily identify. Having said that just seeing it on a fence post or painted on a tree as you go by might only garner a quick glance and an odd look.

It started in Arkansas in 1989 and by 1997, Texas had adopted the “purple paint rule” as an act of legal legislation. As Jonathan Kennedy, of, says in this video, “The reason they did that is they were trying to keep landowners from constantly having to replace signs.”

Originally landowners were required to have a “no trespassing” or other sign posted to explain the purple paint, but only one year later that rule was rescinded. The law states that the paint must be marked in vertical lines a minimum of eight inches long and at least one inch wide.

The marked posts or even trees must have clearly visible paint and that paint must be placed between three and five feet from the ground. Other states with purple paint rules include Kansas, Arizona, Montana, Arkansas, Idaho, Florida, Maine, North Carolina, Missouri, and Illinois.

No matter what state you are in “posted” and other no trespassing signs can be a headache for landowners to constantly replace. Sometimes they just wear out and sometimes trespassers use them for target practice.

Now we just need more states to get in on the purple paint rule. The only thing left to be done is to share what the meaning of the purple paint rule so everyone knows!
