Safety orange (also known as blaze orange, vivid orange, OSHA orange, hunter orange, or Caltrans orange) is a hue. 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 hunting during the rifle season, and is also used for quail hunting. Most places, such as construction sites, use safety orange to help ensure the safety of others.

ANSI standard Z535.1-1998 states how safety orange is defined in the following notation systems:
- 5.0YR (Hue) 6.0/15 (Value/Chroma)
- Approximate PMS (Pantone) Color (mixing directions):
- Pantone Number
- CIE Data:
- x = 0.5510 y = 0.4214 Y% = 30.05
The closest CIE color point that is still in the sRGB gamut is x = 0.54091, y = 0.40869, Y% = 30.05, corresponding to the sRGB-255 coordinates (232, 118, 0).
The Adobe RGB color space is larger than the sRGB color space; the closest "safety orange" CIE color point that is still in the Adobe RGB gamut is x = 0.54467, y = 0.41424, Y% = 30.05, corresponding to the AdobeRGB-255 coordinates (206, 118, 0).
Safety orange is the color usually used in the United States for traffic cones (starting in 1961), 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.
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. Hunter orange is also the color of hats, caps, and other safety wear required to be worn while hunting in most US states.
Orange vests using colors such as safety orange as high visibility clothing may be commonly worn by workers in the US, but this is not merely a legal standard but can be influenced by culture. Since such colored patterned gear is easily produced, it can be assigned any kind of meaning. In Indonesia, it is commonly worn by parking attendants. Similarly in Thailand, it is used by motorcycle taxi workers.
