What is the correct way to check if the player is on a certain team?

local fakeChar = game.ServerStorage.PeasantChar -- The character to load
local respawnTime = 2.5 -- How many seconds the player remains dead before they respawn

if game.Players.LocalPlayer.TeamColor == "Brown" then
	game.Players.CharacterAutoLoads = false -- Disable default character loading
else
	game.Players.CharacterAutoLoads = true
end	

function playerAdded(player)
	if player.Character and player.Character.Parent then -- Destroy an already-existing character
		player.Character:Destroy()
	end

	while player.Parent do -- Repeat until they leave the game
		loadChar(player) -- Method waits until they die
		wait(respawnTime)
	end
end

function loadChar(player)
	local char = fakeChar:clone()
	char.Name = player.Name

	local humanoid
	for i, child in pairs(char:GetChildren()) do -- Find the humanoid
		if child.ClassName == "Humanoid" then
			humanoid = child
			break
		end
	end

	if not humanoid then -- If no humanoid was found, make one
		humanoid = Instance.new("Humanoid", char)
	end

	player.Character = char
	char.Parent = game.Workspace
	humanoid.Died:wait() -- Wait until they die
end

game.Players.PlayerAdded:connect(playerAdded)

for i, player in pairs(game.Players:GetPlayers()) do -- Play Solo support
	if player.Character then
		player.Character:Destroy()
	end

	playerAdded(player)
end

I am trying to make it so that unless you are on the teamcolor brown, your character does not auto load, but I am getting an error on line 4:" ServerScriptService.CharLoader:4: attempt to index nil with 'TeamColor' " Could someone please explain the correct way to check if the player is on a certain team?
