Ahri Ultimate Skin Idea Plz Riot!!!

My idea for an Ahri Ultimate skin is pretty simple to explain but it would probably be difficult to make. I know there are seven colors of the rainbow red, orange, yellow, green, light blue, dark blue, and purple. With this Skin each of the tails should be a different color of the rainbow with the added colors of pink and white to substitute for the last two tails. Whenever Ahri throws out her Q her outfit should change a different color in a specific order. Maybe like Red, Pink, orange, yellow, green, light blue, dark blue, purple then white. Her W Could be the same color as her W and her charm could be the next color she would change into. I'm not a great artist so I don't have a visual representation but just an idea. If the skin isn't made exactly like that something close would still be as cool! p.s
