Jet A

Jet A you smell and put a drop on a white piece of paper. Avgas
evaporates, Jet A leaves a ring.

the fuel strainer?

Some of the newest testers have a ball that sinks in Avgas and floats in JetA
(and water).

Please, please go DO the EXPERIMENT. It does NOT TURN GRAY!

The CHEMISTRY of the colored fuels will turn them CLEAR when mixed.

Mixing 100LL and Jet A will look very light blue, but smell wrong and
feel oily.

Mixing fuels (and associated dyes) doesn't do anything weird
chemistry-wise. 100LL + JetA will just dilute the blue dye and the
mixture will look a light blue like Jer said. So if you mix 80 + 100LL
you get purple (red + blue). Try it, no fuel dye combination makes
gray.
