If an arrow was created by commands, it emits blue effect particles.
Also works with normal arrows (shot with bow), after quitting and re-entering the world.
It only works with standard arrows, not with tipped/spectral arrows.
How to reproduce:
Create a new world in creative mode
Shoot an arrow with a bow
Quit
Re-enter
Go to creative mode
Fly up
Type this command: /summon arrow ~ ~-1 ~
Go down again
