What color is the 100LL Avgas grade?

Explanation:
Color coding helps prevent misfueling by letting technicians and pilots identify the fuel grade at a glance. 100LL Avgas is dyed blue, so the blue color marks this specific low-lead aviation gasoline grade. This visual cue distinguishes it from other aviation fuels and from other grades that use different colors. When you see blue, you’re looking at the 100LL grade, which is important for matching the fuel to the engine’s requirements.
