Fluorescent "Blaze" Orange Requirements
Hunters must wear on the upper portion of their body and head a minimum of 500-square inches of daylight fluorescent orange (blaze orange), visible front and back, while hunting big game except on archery-only and turkey hunts. (A hat and vest fulfills requirements.) Blaze orange camo is legal if it contains 500 square inches of fluorescent orange. In those areas where the archery-only deer season dates overlap with another big game gun season (i. e. bear or boar), archers are required to wear 500 square inches of daylight fluorescent orange (TCA-70-4-124).
