Aro is shorthand for aromantic, although some people think aro is more inclusive than just aromanticity alone.
I based the concept of the flag by InspectorCaracal via tootplanet.space, even though that white in aromantic flag does not mean alloromanticism/allies, it represented qplatonic relationships, aesthetic and platonic attractions, but this isn’t necessary for being aro.
In the ace flag, black represented attraction nullity, so the lack of it, in the aro flags this used to represent sexuality spectrum (sexual orientations) OR alloromantics rejecting traditional ideas of romance. So now I made another one without black:

Darker green (the opposite color of red, a color typically associated with romanticism) represents the aromanticism while the lighter one the aro spectrum, as well as grey-aromantics and demiromantics (amative orientations), but could also represent the aro-spec community as in the asexual purple.
Note that I put two greens to not iterate with the naturist and neutrois flags. – Ap
