Figured how to fix it i was missing the "Color"...
local Blue = script.Parent while true do Blue.Color = Color3.fromRGB(255, 0, 0) wait(1) Blue.Color = Color3.fromRGB(234, 255, 0) wait(1) Blue.Color = Color3.fromRGB(0, 16, 176) wait(1) end
Change "script.Parent" on your variable to "script.Parent.Color" I know someone already answered this, but it's faster than doing Blue.Color.
You have to change the Color property of Blue, not Blue itself.
Blue.Color = Color3.fromRGB()
