How would I detect for there being another team with the same teamcolor?

Hello! I need to figure out how to make a "Create Team" system, I currently have a gui and everything, however i need to check if there are other teams of the same teamcolor. I tried using a for loop which didn't work, but i may have messed it up or something. Along with that, im running this by using a localscript to fire a remote event which leads to this.

function createcrew(player,color)
	print("buy")
	if player.leaderstats.Doubloons.Value >= 5 then
		
		print("money")
		player.leaderstats.Doubloons.Value = player.leaderstats.Doubloons.Value - 5
		local team = Instance.new("Team")
		team.AutoAssignable = false
		team.TeamColor = color
		team.Parent = game.Teams
		team.Name = player.Name.."'s Crew"
		player.Team = team
		player.Neutral = false
		local owner = Instance.new("StringValue")
		owner.Name = "Owner"
		owner.Value = player.Name
		owner.Parent = team
		
		
		
	end
	
	
end
game.ReplicatedStorage.CreateCrew.OnServerEvent:Connect(createcrew)
