How do I make These 2 Scripts only Functional for Players of a Group and Allies of a Group?

Players of a Group Script

local Player = script.Parent.Parent.Parent.Parent.Parent
local teamcolor = "Bright green"

function onClick()
	if Player.TeamColor == BrickColor.new(teamcolor) then
	return
	else
	Player.TeamColor = BrickColor.new(teamcolor)
	Player.Character.Humanoid.Health = 0
	end
end

script.Parent.MouseButton1Down:connect(onClick)

Allies of a Group Script

local Player = script.Parent.Parent.Parent.Parent.Parent
local teamcolor = "Bright blue"

function onClick()
	if Player.TeamColor == BrickColor.new(teamcolor) then
	return
	else
	Player.TeamColor = BrickColor.new(teamcolor)
	Player.Character.Humanoid.Health = 0
	end
end

script.Parent.MouseButton1Down:connect(onClick)
