How do i make a brick's color change really smoothly?

If someone wants to make this script simpler, go ahead but here's a basic understanding of it (I'm not that good of a coder but tried) :

while true do
for i = 1, 255 do
	script.Parent.Color = Color3.fromRGB(255, i, 0)
	wait(.00001)
end
for i = 255, 0, -1 do
	script.Parent.Color = Color3.fromRGB(i, 255, 0)
	wait(.00001)
end
for i = 0, 255 do
	script.Parent.Color = Color3.fromRGB(0, 255, i)
	wait(.00001)
end
for i = 255, 0, -1 do
	script.Parent.Color = Color3.fromRGB(0, i, 255)
	wait(.00001)
end
for i = 0, 255 do
	script.Parent.Color = Color3.fromRGB(i, 0, 255)
	wait(.00001)
end
for i = 255, 0, -1 do
	script.Parent.Color = Color3.fromRGB(255, 0, i)
	wait(.00001)
end
end

It basically just loops a rainbow
