How can I make a animated rainbow block?

Title. Haven’t found anyone cover this.

Insert a part, apply the Neon material, add a script to the part with code that changes the BrickColor property over time using the HSV color model, and playtest the game to see the animated rainbow effect Xx

Could you kindly show me how that works, I’ve never used this HSV model before. Thank you :D_

The HSV color model in Roblox represents colors based on hue, saturation, and value, and by modifying the hue component over time using a script, you can create an animated rainbow effect on a part. Here’s a code example Xx

local part = script.Parent

local hue = 0
local hueIncrement = 0.01

while true do
	wait(0.1)
	
	hue = hue + hueIncrement
	if hue >= 1 then
		hue = 0
	end
	
	part.BrickColor = BrickColor.new().HSV(hue, 1, 1)
end

'HSV' is not a valid member of BrickColor

Fixed your code and made it look a bit seamless.

local part = script.Parent -- ur part here

local hue = 0
local hueIncrement = 0.005 -- adjust for color speed

game:GetService("RunService").Heartbeat:Connect(function()
	hue = hue + hueIncrement
	if hue >= 1 then
		hue = 0
	end

	local r, g, b = Color3.fromHSV(hue, 1, 1):ToHSV()
	local color = Color3.fromHSV((hue + hueIncrement) % 1, 1, 1):Lerp(Color3.new(r, g, b), hue % (1 / hueIncrement))
	part.BrickColor = BrickColor.new(color)
end)

Actually I made my own, here’s a (probably) better and more simple code:

local b = script.Parent

local x = 0

while true do
	b.Color = Color3.fromHSV(x,1,1)
	x = x + 1/255
	if x >=1 then
		x=0
	end
	task.wait()
end

while true do task.wait() end is the equivalent to using heartbeat.

Glad you could figure it out yourself. Good luck.
