How does one make spot light change color?

go inside the Spotlight properties and change the color by pressing on the color pallet and changing the color from there or if you want to do it with a script put a server script inside the Spotlight and put this inside the script :

local Spotlight = script.Parent

Spotlight.Color = Color3.fromRGB(25,25,25) -- Numbers represent color values

or if you want to randomize if you can do

local Spotlight = script.Parent

game:GetService("RunService").Stepped:Connect(function()
      Spotlight.Color = Color3.fromRGB(math.random(),math.random(),math.random)
end)

Hello. To change SpotLight color go to:

SpotLight » Properties » Color

To change it with a Script use:

SpotLight = script.Parent.SpotLight

SpotLight.Color = Color3.fromRGB(0,0,0)

Here is a Script to change the color.

SpotLight = script.Parent.SpotLight

while wait(0.1) do
    Number1 = math.random(1,999)
    Number2 = math.random(1,999)
    Number3 = math.random(1,999)
    SpotLight.Color = Color3.fromRGB(Number1,Number2,Number3)
end
