Hello Indigo Child! We love using Poseidon with Purple Rain to get this cobalt shade. It's one of our favorite bright blues! As a bonus, the Purple Rain can help combat the green fades you can get on pale yellow hair base. Use 1/3 Purple Rain and 2/3 Poseidon to transform your hair into a rhapsody of blue.
