  1. What do you want to achieve? hello am new to scripting, and i can’t make my neon part colour change repeatedly
local a = script.Parent.a
local b = script.Parent.b
local c = script.Parent.c
local d = script.Parent.d
local al = a.PointLight
local bl = b.PointLight
local cl = c.PointLight
local dl = d.PointLight
local colors = {red = Color3.fromRGB(255, 0, 0), green = Color3.fromRGB(40, 127, 71),}
local lcolors = { redl = Color3.fromRGB(130, 27, 27), greenl = Color3.fromRGB(0, 170, 0)}
local randomlcolor = math.random(1,lcolors)
local randomcolor = math.random(1,colors)
while true do
	a.Color = randomcolor
	al.Color = randomlcolor
	task.wait(0.1)
	b.Color = randomcolor
	bl.Color = randomlcolor
	task.wait(0.1)
	c.Color = randomcolor
	cl.Color = randomlcolor
	task.wait(0.1)
	d.Color = randomcolor
	dl.Color = randomlcolor
	task.wait(0.1)
end

am trying to make the lights for the part and the part itself change colour there are exactly 4 parts and 4 spot lights, anything that has an l in it it is for the light and am also trying to make it randomly change forever, thanks

you need to do this:

while true do
    local randomlcolor = math.random(1,lcolors)
    local randomcolor = math.random(1,colors)
	a.Color = randomcolor
	al.Color = randomlcolor
	task.wait(0.1)
	b.Color = randomcolor
	bl.Color = randomlcolor
	task.wait(0.1)
	c.Color = randomcolor
	cl.Color = randomlcolor
	task.wait(0.1)
	d.Color = randomcolor
	dl.Color = randomlcolor
	task.wait(0.1)
end

also I would use a for loop

and this code doesn’t even work, you’re changing it to a number
wait I’m gonna redo the code

		part.Color = randomPartColor
		light.Color = randomLightColor
		task.wait(0.1)
	end

local colors = {Color3.fromRGB(255, 0, 0), Color3.fromRGB(40, 127, 71)} -- define colors
local lcolors = {Color3.fromRGB(130, 27, 27), Color3.fromRGB(0, 170, 0)} -- define light colors

-- colors and lcolors are arrays because there is no key defined (i.e. {hello = "world"})

local parts = {script.Parent.a, script.Parent.b, script.Parent.c, script.Parent.d} -- get the parts
local lights = {} -- to be filled

for i,v in parts do -- loop through all the parts (a,b,c,d)
	if v:FindFirstChildOfClass("PointLight") then -- if the part has a pointlight
		lights[v] = v:FindFirstChildOfClass("PointLight") -- add the light to the lights table
	end
end

while true do -- while loop
	for i,v in parts do -- loop through parts
		local randomColor, randomLightColor = math.random(#colors), math.random(#lcolors) -- get colors
		v.Color = randomColor -- assign color
		if lights[v] then -- check if a light exists
			lights[v].Color = randomLightColor -- assign the light color
		end
		task.wait(.1) -- wait 0.1s
	end
	task.wait(.1) -- wait 0.1s
end

This should fix the problem. Be sure to learn from this code so your scripting skills become better! I labeled all the lines so you understand whats going on.

function getRandomColor(colorTable : {}) : Color3
	local keys = {}

		table.insert(keys, key)
	end
	local randomKey = keys[math.random(1, #keys)]
	return colorTable[randomKey]
end

	al.Color = randomlcolor
	task.wait(0.1)

Oh yeahhhh mb :skull:

local randomColor, randomLightColor = math.random(#colors), math.random(#lcolors) -- get colors
v.Color = colors[randomColor] -- assign color
if lights[v] then -- check if a light exists
	lights[v].Color = lcolors[randomLightColor ] -- assign the light color
end
