What colour is AVGAS?

Explanation:
The idea being tested is how aviation gasoline is color-coded to identify grade. AVGAS isn’t colorless—the dyes help ground crews and pilots avoid misfueling. In practice, the common low-lead grade is blue (100LL), and another higher-octane grade is green (100/130). So the color you’d expect for AVGAS can be blue or green, depending on the specific grade. That’s why the option listing both green and blue is the correct one. Other colors are used for different fuels, so they don’t apply here.
