Which color represents the 100/130 Avgas grade?

Explanation:
Color coding in aviation fuels helps prevent misfueling by letting crews quickly identify the grade. Each grade is dyed a distinct color, so the appearance of the fuel at the pump or in containers acts as a safety cue. The 100/130 Avgas grade is green, which differentiates it from other grades like 100LL, which is blue. This green cue helps ensure the right fuel goes into the aircraft, since the octane characteristics of each grade affect engine performance and safety. So when you see green fuel, you’re looking at 100/130 Avgas.
