Spectate Gui: only spectate certain teams. Any help?

If there a way of doing this script to where it only is able to spectate a certain team and if that player is killed it will move onto the next player. I'm wanting it to only spectate the Bright blue and Bright red team players.

Here is the script:

cam = game.Workspace.CurrentCamera

local bar = script.Parent.Bar
local title = bar.Title
local prev = bar.Previous
local nex = bar.Next
local button = script.Parent.Button

function get()
	for _,v in pairs(game.Players:GetPlayers())do
		if v.Name == title.Text then
			return(_)
		end
	end
end


local debounce = false
button.MouseButton1Click:connect(function()
	if debounce == false then debounce = true
		bar:TweenPosition(UDim2.new(.5,-100,0.88,-50),"In","Linear",1,true)
		pcall(function()
				title.Text = game.Players:GetPlayerFromCharacter(cam.CameraSubject.Parent).Name
		end)
	elseif debounce == true then debounce = false
		pcall(function() cam.CameraSubject = game.Players.LocalPlayer.Character.Humanoid end)
			bar:TweenPosition(UDim2.new(-1,-100,0.88,-50),"In","Linear",1,true)
		end
end)

prev.MouseButton1Click:connect(function()
	wait(.1)
	local players = game.Players:GetPlayers()
	local num = get()
	if not pcall(function() 
		cam.CameraSubject = players[num-1].Character.Humanoid
		end) then
		cam.CameraSubject = players[#players].Character.Humanoid
	end
pcall(function()
				title.Text = game.Players:GetPlayerFromCharacter(cam.CameraSubject.Parent).Name
		end)
end)

nex.MouseButton1Click:connect(function()
	wait(.1)
	local players = game.Players:GetPlayers()
	local num = get()
	if not pcall(function() 
		cam.CameraSubject = players[num+1].Character.Humanoid
		end) then
		cam.CameraSubject = players[1].Character.Humanoid
	end
pcall(function()
				title.Text = game.Players:GetPlayerFromCharacter(cam.CameraSubject.Parent).Name
		end)
end)
