How can I make something that changes when you click it two times?

For example, I have a brick that when you click it once, the color is red, you click it a second time and it's yellow, a third time it's blue and the fourth time it goes back to red and the cycle repeats. How can I archieve this?

As Ponytails2017 said, this is not a request site. As you did make an effort to post your attempts, I am happy to help. Just remember in the future to follow the guildelines.

local clickDetector = script.Parent -- instance of ClickDetector
local uses = 0

clickDetector.MouseClick:Connect(function(player)
	uses = uses + 1
	if uses == 1 then
		clickDetector.Parent.BrickColor = BrickColor.new("Bright red")
	elseif uses == 2 then
		clickDetector.Parent.BrickColor = BrickColor.new("Baby blue")
		uses = 0 -- reset the count after the 2 clicks to continue checking
	end
end)

You should check this out for more information: ClickDetector API

EDIT

I noticed I forgot to change 'script.Parent.BrickColor' to 'clickDetector.Parent.BrickColor'. It has been fixed.

write a variable called uses or something

local uses = 0
if uses == 1 then
uses += 1
(change color here)
elseif uses == 2 then
uses += 1
(change color here)
elseif uses == 3 then
uses += 1
(change color here)
end

-- and repeat, inset this inside of the click detector function

This is not a request site dude, try it first then if it doesn't work we can help you. https://scriptinghelpers.org/help/community-guidelines

Tried to make it myself, but this doesn't work still.

while wait(1) do
	local value = 0
	if value == 0 then
		script.Parent.BrickColor = BrickColor.new("Bright red")
		value = value + 1
	end
	if value ==  1 then
		script.Parent.BrickColor = BrickColor.new("Bright yellow")
		value = value + 1
	end
	if value == 2 then
		script.Parent.BrickColor = BrickColor.new("Baby blue")
		value = value - 1
	end
end
