A safety orange warning sign for road construction sites.

Safety orange (also known as blaze orange, vivid orange, Caltrans orange, or Omaha orange) is a hue. Its deeper, more saturated shade is known as international orange. Safety orange is used to set objects apart from their surroundings, particularly in complementary contrast to the azure color of the sky (azure is the complementary color of orange, and therefore there is a very strong contrast between the two colors). The color is commonly used for high-visibility clothing to be worn while hunting.

ANSI standard Z535.1–1998 states how safety orange is defined in the following notation systems:

• Munsell Notation:

5.0YR (Hue) 6.0/15 (Value/Chroma)

• CIE Data:

x=0.5510 y=0.4214 Y%=30.05

• Approximate PMS (Pantone) Color (actually, mixing directions):

13 parts Yellow, 3 parts Warm Red, 1/4 part Black

Safety orange is the same color as blaze orange, the shade of orange (Color No. 12199) required by United States law (U.S. Code of Federal Regulations, Title 15 Commerce and Foreign Trade, Section 1150.3) to be on the tips of barrels of replica guns such as airsoft guns, and cap or toy guns.

Safety orange is the color usually used in the United States for traffic cones, stanchions, barrels, and other construction zone marking devices. OSHA requires that certain construction equipment must be painted safety orange. Two large trucking companies, Allied Van Lines and Schneider National, paint their trucks and trailers safety orange. In Europe, Dayglo orange (or "luminous orange"; RAL 2005) serves the same purpose.
