i not very good at explanations but ima try to explain how i made this made it with 2 simples steps: 1: made a costume with 4 gradiants that would go to red to various color before returning to red again, which for example the first gradiant goes to red to yellow, the second goes to yellow to cyan the third goes cyan to pink and the last pink to red 2: added a change effect by (number) block and looped it and that's pretty much it
