How can I make random teams assign?

I want to make players get randomly assigned to teams. I have one script for this, but its not really that good. Is there a better way to do this? Here is my script:

local assign = 1
for i,v in pairs(game.Players:GetChildren()) do
if assign = 1 then
assign = 2 
v.Team.BrickColor = BrickColor.new("Black")
else

assign = 1
v.Team.BrickColor = BrickColor.new("White")
end

I hope this works for you, because it worked for me.

for key, value in pairs(game.Players:GetChildren()) do
	local TeamAssign = math.random(1, 3) --custom amount of teams
	if TeamAssign == 1 then
		value.TeamColor = BrickColor.new("Bright red")--your team here
        elseif TeamAssign == 2 then
	       value.TeamColor = BrickColor.new("Bright blue") --your team here 
        elseif TeamAssign == 3 then
	       value.TeamColor = BrickColor.new("Bright green")--your team here
        end
end

Here you go. Make sure that every team you put in this script exists in your game. Sincerely, DominusInfinitus
