Their appearance has them wearing white cloaks and what resembles gas masks, as well as apparently being green.
Relation with Frieza's race
This would be fitting given their relationship with the early Saiyans, as well as their small humanoid bodies concealed underneath their cloaks; as evidenced by Frieza's ancestor Chilled using a hooded cloak when encountering Bardock on Planet Plant in Dragon Ball: Episode of Bardock. Also, the one who destroyed Planet Vegeta was shown wearing a hooded cloak in an early flashback and we later learn that the one who destroyed the planet was Frieza himself.
In addition, it is to be noted that the name of the race partially derives from negative temperatures (in this case, Arctic), like the names of the members of Frieza's race.
It is worth noting however that the name 'Arcosian' is a term exclusive to the English dub.
