How to make cycling rainbow bricks?

Hello, I want to make rainbow bricks that cycle together. This is a gif of what I mean.

Make a table of all the parts

And a table of colors

Loop through the table of parts in order

And each time pick the next color in the table of colors - set the current part to that color

If you reach the end of the color table, wrap around to its start

If you name them in order and parent them to a fixed parent this script can make effect you showed :

local Parts = ["Parts Parent Here"]:GetChildren()
local offset = 0

while task.wait(1) do
	offset += 1
	offset %= #Parts
	
	for index, part in Parts do
		local hue = ((offset + index) / #Parts) % 1
		part.Color = Color3.fromHSV(hue, 1, 1)
	end

To make it faster you can reduce the wait value, adding more parts will make the effect look smoother.

This should do it.

RainbowColorBlocks.rbxl (41.6 KB)

local partList = {}
local numParts = #workspace.Parts:GetChildren()

for n = 1,numParts do
	local part = workspace.Parts:FindFirstChild("Part_"..n)
	table.insert(partList,part)
end

local colorList = {}
for n = 1,numParts do
	local hue = (n / numParts) % 1
	table.insert(colorList, Color3.fromHSV(hue, 1, 1))
end

local colorIndex = 1
while task.wait(.1) do
	
	for n = 1,#partList do
		local index = colorIndex+n
		while index > #colorList do
			index = index - #colorList
		end
		partList[n].Color = colorList[index]
	end
	
	colorIndex += 1
	colorIndex %= #colorList
end

You can have the colorList be auto filled, as in the code, or you can specify your own colors.
Also note, the number of colors does NOT have to match the number of parts.

You could set color list to be

local colorList = {
	Color3.new(1, 0, 0),
	Color3.new(0, 0, 1)
}

and it would work fine with the 7 blocks.
