Help with assigning players to a random team?

I have 3 Teams in my game (Lobby, Blue and Red). When you join the game you are as "Lobby" but when the game starts, I want it to assign random players to a team, either blue are red. Idk how to do this, please help. Thanks!

function AssignTeam()
	for i, v in pairs(game.Players:GetPlayers()) do
		if v:FindFirstChild("TeamColor") == BrickColor.new("Medium stone grey") then
    			--not sure what to put here
		end
	end	
end

How to assign players to random teams? Got it. First of all, use GetService for players instead just to be safe. So your line 02 should be for i, v in next, game:GetService('Players'):GetPlayers() do.

Create a variable for one of the team, so the loop knows when to add the player to that team or the other. local redTeam = true;.

For each loop check the new variable and switch it with redTeam = not redTeam.

Also to check for team color use v.TeamColor not v:FindFirstChild("TeamColor")

Whole code:

local redTeam = true;

function AssignTeam()
    for i, v in next, game:GetService('Players'):GetPlayers() do
        if v.TeamColor == BrickColor.new("Medium stone grey") then
                if redTeam then
			v.TeamColor = BrickColor.new('Bright red');
		else
			v.TeamColor = BrickColor.new('Bright blue');
		end
		redTeam = not redTeam;
        end
    end 
end

I assumed you used the default red and blue Brickcolors

This is what i do

local Teams = {'Yellow'.'Girrafe'} -- idk, you can add more teams and this would still work

function ChooseTeam()
local num = math.random(1,#Teams) -- num of items in the table 'Teams'
local ChosenTeam = Teams[num]
print(ChosenTeam) --shud print Yellow or Girrafe

player.TeamColor = game.Teams[ChosenTeam].TeamColor -- assuming you already have the player




end
