How about a SurfaceLight color that equals to brick color?

Working with some lighting for a friends game but I have continued to fail to have my lights match their brick color. The brick color pattern is there below. I tried to change it so the lights color would have the same pattern. Of course it didn't work ,_,

while true do
wait(0.5)
script.Parent.Color = BrickColor.new("Bright red")
wait(0.5)
script.Parent.Color = BrickColor.new("Bright orange")
wait(0.5)
script.Parent.Color = BrickColor.new("Bright yellow")
wait(0.5)
script.Parent.Color = BrickColor.new("Bright green")
wait(0.5)
script.Parent.Color = BrickColor.new("Bright blue")
wait(0.5)
script.Parent.Color = BrickColor.new("Bright violet")
end

While Leamir's answer is valid and correct, it would be much more efficient to do

script.Parent.Parent:Changed:Connect(function(property)
	if property == "Color" then
		script.Parent.Color = script.Parent.Parent.Color
	end
end)
