Safety Orange (also known as Blazing Orange, Bright Orange, OSHA Orange, Hunter Orange or Caltrans Orange) is a dye. Safety orange is used to distinguish objects in your environment, especially in complementary contrast to the blue sky. (Blue is the complementary color of orange, so there is a strong contrast between the two colors.) The highly visible color is often used for hunting during gun season and also for quail hunting. Places like construction sites use this orange to protect others. ANSI Z535.1–1998 specifies how Safety Orange is defined in the following notation systems:
- Munsell Notation: 5.0YR (hue) 6.0/15 (value/chroma)
- Approximate PMS (Pantone) Color (Mix Direction): 13 parts yellow, 3 parts, 1⁄4 parts black
- Pantone number 152
- CIE data: x = 0.5510 y = 0.4214 Y% = 30.05 Note that this CIE color point is outside the gamut of common color spaces such as sRGB or Adobe RGB. The closest CIE color point yet in the sRGB color space is x=0.54091, y=0.40869, Y%=30.05, which corresponds to the coordinates sRGB-255 (232, 118, 0). The Adobe RGB color space is larger than the sRGB color space; The closest CIE “safety orange” color point, also in the Adobe RGB color space, is x = 0.54467, y = 0.41424, Y % = 30.05 %, which corresponds to AdobeRGB coordinates 255 (206, 118, 0). Safety orange is the commonly used color in the United States for traffic cones (since 1961), posts, barrels, and other construction site markings. OSHA requires some construction equipment to be painted a safety orange color. Two major trucking companies, Allied Van Lines and Schneider National, are painting 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 number 12199) required by the United States Code of Federal Regulations, Title 15 Commerce and Foreign Trade, Section 1150.3 to appear on replica firearms muzzle tips , such as airsoft guns and caps or toy guns. Hunter Orange is also the color of hats, caps, and other safety gear that must be worn for hunting in most US states.
