How do I locate the player using the GUI's character without local scripts?

I'm trying to make a GUI that when you press a button it changes your body colors and face to the pre-set decal and body colors inside the button, it's done with local scripts but the problem is well, its local, nobody else can see it which defeats the point, so how would I find the player using the GUI's character without these local scripts? Heres my code:

script.Parent.MouseButton1Down:Connect(function()
	game.Players.LocalPlayer.Character:FindFirstChild("Body Colors"):Destroy()
	local colors = script.Parent:FindFirstChild("Body Colors"):Clone()
	colors.Parent = game.Players.LocalPlayer.Character
	game.Players.LocalPlayer.Character.Head.face:Destroy()
	local face = script.Parent.face:Clone()
	face.Parent = game.Players.LocalPlayer.Character.Head
end)

Utilizing RemoteEvents, when the buttons is being clicked, Fire a RemoteEvent. A RemoteEvent should be located in ReplicatedStorage. In a server script, change the BodyColors.
