Fixing broken team changing script?

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

function ButtonClicked()
	if getTeamPlayers(script.Parent.BrickColor) <15 then
		game.Players.LocalPlayer.TeamColor = BrickColor.new(script.Parent.BrickColor)
		-- Here we need a way to kill the player or teleport him to a spawn with the "Bright blue" color (script.Parent.BrickColor)
	end
end

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

-- 12:02:09.547 - Workspace.Civilians.Button.TeamScript:4: bad argument #1 to 'new' (Color3 expected, got BrickColor)

The above comment shows the error it returns in the output. I have no clue what isn't working, as the top function checks amount of players in a team and the second uses it to check if the team has any opening and assigns the player who pressed the button if one exists. Why is it broken and how to fix it?
