What colors are associated with 100 LL aviation fuel?

The color associated with 100 LL aviation fuel is blue. This specific color coding serves practical purposes in aviation safety and helps pilots and ground personnel easily distinguish between different types of aviation fuel.

Color coding is essential in preventing fuel misidentification, which could lead to serious safety hazards if a pilot inadvertently fuels an aircraft with the wrong type of fuel. 100 LL, which stands for low-lead, is used primarily in piston-engine aircraft and is distinctly colored blue to differentiate it from other fuels, such as 100 grade fuel, which is dyed green, and mogas, often colored red or yellow. This system of color coding helps ensure that fuel handling is done safely and correctly.
