How to make a button turn green when you click it?

messing around with click detectors and i made a button. Im trying to make it turn green when you press it and stay green.

local cd = script.Parent
local light = game.Workspace.WarningLight
local Button = game.Workspace.Button.Buttn
cd.MouseHoverEnter:Connect(function()
	Button.BrickColor = BrickColor.new ("Bright red")
end)
cd.MouseHoverLeave:Connect(function()	
	Button.BrickColor = BrickColor.new ("Institutional white")
end)
cd.MouseClick:Connect(function()
	light.BrickColor = BrickColor.new ("Institutional white")
	game.Workspace.WarningLight:Destroy()
	Button.BrickColor = BrickColor.new ("Lime green") --turns it green until your cursor leaves the button
end)

Trying to make it stay green

Do you want it to turn green when somebody clicks it? if so then it would be

local ClickDetector = script.Parent.ClickDetector

ClickDetector.MouseClick:Connect(function()
script.Parent.BrickColor = BrickColor.new("Lime Green")
end)
