According to OSHA, this is what each safety color means (listed from highest degree of danger to least):

1. 1.Red Traffic Cones-Danger. For OSHA, red connotes imminent danger with the chance of serious injury or death.
2. 2.Traffic Orange Traffic Cones-Warning. The color Orange means there is a potential danger of serious injury or death.
3. 3.Yellow Traffic Cones-Caution. Yellow also portends potential danger, but, according to OSHA, the risk is lessened to general injury.
4. 4.Kelly Green Traffic Cones-Safety Equipment. OSHA has assigned green to first-aid stations that feature emergency information, eye wash or other safety equipment. Green is also commonly used at athletic events, especially track and field.
5. 5.Navy Blue Traffic Cones-Notice. OSHA uses blue to denote important information that is non-hazardous. Blue is also used to designate Handicapped-only spaces.
6. 6.White Traffic Cones. White marks areas that are considered safe. White is also a good backdrop for logos, or to indicate the location of entrances, restrooms, etc.

Additional traffic cone colors are also available. These do not carry any OSHA designation, but over years of usage, the colors do carry a special meaning.

• 1.Safety Pink Traffic Cones. Most people immediately recognize safety pink as the global designated color of the breast cancer walks. Again, we make chain cone connectors and plastic chain to exactly match the pink traffic cones.
• 2.Safety Green Traffic Cones. These are also called lime green, and they are a cross between yellow and green. Even though this color is not specifically designated by OSHA as a safety color, these traffic cones match the safety vest that many highway and construction workers wear. Safety green is a color that is very visible to the human eye.
• 3.Sky Blue Traffic Cones. Sky blue does not have a common meaning, but it is a vibrant color that could be used for parties, corporate events, and would be attractive at a baby shower.
