How do you allow people through Door restrictions?

I tried different codes GetChildren, GetPlayers, IsInGroup, game.Players.LocalPlayers and it just wouldn't allow anyone to go through the door. I just want TeamColor "Really Blue" also known as Team "ct" to get through the door

local leaderboard = script.Parent.Parent:WaitForChild('leaderboard')
local door = script.Parent

function open()
	door.CanCollide = false 
	for transparency = 0, 1, .1 do
		door.Transparency = transparency
		wait(.1)
	end
end
 
function close()
	for transparency = 1, 0, -.1 do
		door.Transparency = transparency
		wait(.1)
	end
	door.CanCollide = true
end
 

function get_player(part)
	for _, player in ipairs(game.Players:GetPlayers()) do
		if part:IsDescendantOf(player.Character) then
			return player
		end
	end
end
 
 
door.Touched:connect(function(part)
	local player = get_player(part)
	if not player then return end
 
	local allow = (
		game.Players:GetChildren().TeamColor == 'Really blue' --THIS LINE IS KILLING ME
	)
	if allow then
		open()
		delay(4, close)
	elseif not allow then
		game.Players.LocalPlayer:LoadCharacter()
	end
end)

Oh and if you are going to reply don't reply to me about "IsInGroup".
