No Trespassing” sign. Ignoring them can result in criminal trespass charges, even if no signs are present.Why Purple?
Great question! Several practical reasons:
Highly visible year-round—even in snow, mud, or dense foliage
Uncommon in nature, so it stands out (unlike red, which could be rust or clay)
Not used for other property markings (blue = pipeline, orange = survey, etc.)
Long-lasting paint resists fading better than many colors
Does It Apply Everywhere?
No. If you’re in a state without a purple paint
