Why doesn't this script set Color3 to blue, and instead turns it white?

I have a script that plays a sound every time you scroll. There's also a script that allows you to turn off the sound. If the script is disabled, the button turns red, but if the script isn't disabled, it should turn blue. Although it just turns white. Here's the script:

script.Parent.MouseButton1Click:Connect(function()
	if script.Parent.Parent.Parent.Parent.Parent.PlayerScripts.ScrollSound.Disabled == false then
	script.Parent.Parent.Parent.Parent.Parent.PlayerScripts.ScrollSound.Disabled = true
	script.Parent.Text = "Scroll Sound Effect: OFF"
	script.Parent.BackgroundColor3 = Color3.new(255, 0, 0)
	elseif script.Parent.Parent.Parent.Parent.Parent.PlayerScripts.ScrollSound.Disabled == true then
	script.Parent.Parent.Parent.Parent.Parent.PlayerScripts.ScrollSound.Disabled = false
	script.Parent.Text = "Scroll Sound Effect: ON"
	script.Parent.BackgroundColor3 = Color3.new(20, 141, 255)	
	end
end)
