how do i make it so it cycles through colors?

ive always wondered how developers cycle through colors. how do i do that exactley?

If you're learning to code, this is actually a great exercise!

Let's say we have a brick (or a Part in technical terms).

brick = Workspace.Part (if you're confused already, I recommend you read this)

We need a list of the colors to run through. This list is called a table. Define it as a table of Strings:

tableOfColors = {"Really red", "Bright blue", "Bright yellow", "Really black", "Institutional white"} (if you're confused, read this)

We know we set a Part's color by doing this:

brick.BrickColor = BrickColor.new("Really red")

So our goal is just to repalce "Really red" with a value from our table. Let's use the first one:

brick.BrickColor = BrickColor.new(tableOfColors[1])

Now we have a red brick, but we used the tableOfColors to get it! Now we just need to change that 1 so that it counts through to 5, and then resets back to 1. Let's use a loop to do this once per second:

counter = 1
while true do
	brick.BrickColor = BrickColor.new(tableOfColors[counter])

	counter = counter + 1

	wait(1)
end

(If you're confused, read this)

If you run that code, it will work - but it will eventually run into a problem when counter = 6. We only have 5 numbers! Let's add a check to see if we've gone over our limit and reset counter to 1 if we have:

counter = 1
while true do
	if (counter == 6) then
		counter = 1
	end

	brick.BrickColor = BrickColor.new(tableOfColors[counter])

	counter = counter + 1

	wait(1)
end

That's it! The brick will change colors in order!
