How do I change a player's team?

local function getTeamPlayers(teamColor)
local output = {}
for _, player in pairs(game.Players:getPlayers()) do
if (not player.Neutral) and player.TeamColor == BrickColor.new(teamColor) then
table.insert(output, player)
end
end
return output
end

length = function( tab )
    local count = 0 -- increases in accordance with
    --number of entries in provided table
    for index, value in next, tab do
        -- iterates through provided table
        count = count + 1
    end

    return count -- returns total amount of found entries in table `tab`
end

length(getTeamPlayers()) 

function onClicked()
print "test" -- To test if it even gets up to this point
    if (#getTeamPlayers("Bright blue")) < 17 then
        print(#getTeamPlayers("Bright blue"))
        game.Players.LocalPlayer.TeamColor = BrickColor.new("Bright blue") -- This is the broken line
    end
end

script.Parent.ClickDetector.MouseClick:connect(onClicked)

The line to change a player's team isn't working. I have tried lots and lots and things and now I have no idea. How do I change the player who pressed team to Bright blue?
