What grade of aviation gasoline is dyed blue?

Explanation:
Color coding in avgas helps you spot the fuel quickly. The blue dye is used for the 100-octane fuel with low lead content, known as 100LL. LL stands for low lead, and the blue color distinguishes it from other grades that use different colors. So the blue-dyed fuel is the low-lead 100-octane grade.
