Why do the lights turn blue?

I have a script made to make the lights flickering, but instead of turning the lights back to (248, 217, 109) (which is yellow) like the script says to, the lights turn to (8, 39, 147) (which is blue). My script is:

local light = script.Parent.Part.SpotLight
local light2 = script.Parent.Part2.SpotLight
local light3 = script.Parent.Part3.SpotLight
local value = script.Parent.Parent.Parent.PowerOutage.Value

while true do
	wait(math.random(0.5,3))
	if value == false then
			
		light.Brightness = 0
		light.Parent.Material = Enum.Material.Plastic
		light.Color = Color3.new(0, 0, 0)
		
		light2.Brightness = 0
		light2.Parent.Material = Enum.Material.Plastic
		light2.Parent.Color = Color3.new(0, 0, 0)
		
		light3.Brightness = 0
		light3.Parent.Material = Enum.Material.Plastic
		light3.Color = Color3.new(0, 0, 0)
		
		wait(math.random(0.8,1.3))
		
		light.Brightness = 1
		light.Parent.Material = Enum.Material.Neon
		light.Parent.Color = Color3.new(248, 217, 109)
		
		light2.Brightness = 1
		light2.Parent.Material = Enum.Material.Neon
		light2.Parent.Color = Color3.new(248, 217, 109)
		
		light3.Brightness = 1
		light3.Parent.Material = Enum.Material.Neon
		light3.Parent.Color = Color3.new(248, 217, 109)
		
	else
		
		wait(math.random(0.8,1.3))
		
	end
	
end

(The value and checking is for something I'm implementing later)
