How do I make a for loop repeat forever?

I am making a rainbow spiral that changes color. Here's my code:

local CService= game:GetService("CollectionService")

local red= CService:GetTagged("Red")
local orange= CService:GetTagged("Orange")
local yellow= CService:GetTagged("Yellow")
local green= CService:GetTagged("Green")
local blue= CService:GetTagged("BLue")
local purple= CService:GetTagged("Purple")

local RedCycle= coroutine.create(function()
	while true do
		for i,v in pairs(red)do
			v.Color= Color3.fromRGB(213,115,61)  --orange
			v.Color= Color3.fromRGB(255,255,0)
			v.Color= Color3.fromRGB(0,255,0) 
			v.Color= Color3.fromRGB(0,0,255)
			v.Color= Color3.fromRGB(255,0,191)
			wait()
		end
	end
end)

local OrangeCycle= coroutine.create(function()
	while true do
		for i,v in pairs(orange)do
			
			v.Color= Color3.fromRGB(255,255,0)
			v.Color= Color3.fromRGB(0,255,0) 
			v.Color= Color3.fromRGB(0,0,255)
			v.Color= Color3.fromRGB(255,0,191)
			v.Color= Color3.fromRGB(255,0,0)
			v.Color= Color3.fromRGB(213,115,61)
			wait()
		end
	end
end)

local YellowCycle= coroutine.create(function()
	while true do
		for i,v in pairs(yellow)do
			v.Color= Color3.fromRGB(0,255,0) 
			v.Color= Color3.fromRGB(0,0,255)
			v.Color= Color3.fromRGB(255,0,191)
			v.Color= Color3.fromRGB(255,0,0)
			v.Color= Color3.fromRGB(213,115,61)
			v.Color= Color3.fromRGB(255,255,0)
			wait()
		end
	end
end)

local GreenCycle= coroutine.create(function()
	while true do
		for i,v in pairs(green)do
			v.Color= Color3.fromRGB(0,0,255)
			v.Color= Color3.fromRGB(255,0,191)
			v.Color= Color3.fromRGB(255,0,0)
			v.Color= Color3.fromRGB(213,115,61)
			v.Color= Color3.fromRGB(255,255,0)
			v.Color= Color3.fromRGB(0,255,0) 
			wait()
		end
	end
end)

local BlueCycle= coroutine.create(function()
	while true do
		for i,v in pairs(blue)do
			v.Color= Color3.fromRGB(255,0,191)
			v.Color= Color3.fromRGB(255,0,0)
			v.Color= Color3.fromRGB(213,115,61)
			v.Color= Color3.fromRGB(255,255,0)
			v.Color= Color3.fromRGB(0,255,0) 
			v.Color= Color3.fromRGB(0,0,255)
			wait(1)
		end
	end
end)

local PurpleCycle= coroutine.create(function()
		while true do
		for i,v in pairs(purple) do
			v.Color= Color3.fromRGB(255,0,0)
			v.Color= Color3.fromRGB(213,115,61)
			v.Color= Color3.fromRGB(255,255,0)
			v.Color= Color3.fromRGB(0,255,0) 
			v.Color= Color3.fromRGB(0,0,255)
			v.Color= Color3.fromRGB(255,0,191)
			wait(1)
		end
	end
end)

coroutine.resume(RedCycle)
coroutine.resume(OrangeCycle)
coroutine.resume(YellowCycle)
coroutine.resume(GreenCycle)
coroutine.resume(BlueCycle)
coroutine.resume(PurpleCycle)

I will explain. I'm using Collection Service to tag certain parts that start with a certain color and put them all in a coroutine where it keeps changing (for example, anything originally with yellow will go to green, blue, purple, red, orange, and back over and over again. However, this only repeats once, and I don't know how to fix it. I've been trying for over an hour. Thanks.
