While there isn't any official names for the Crew Members, I would say the Green members are Endowment Crew Members (as they improve your bike's abilities), Yellow members are Enviroment Crew Members (as they modify the tracks) and Blue members are Exploration Crew Members (due to how they can help you see further and such) - AuroVee (talk) 16:44, 3 May 2021 (UTC)
