I have transitioned from being a pink head to a blue head. I absolutely love the Sky blue color over the Aqua because it is more blue. But I have mixed reviews with my friends favoring the Aqua. My head looks like the ocean. I had to do 5 tubes of dye overall with the blue though because it's not like the pink and if you miss a spot it's not super noticeable, but because of the contrast between the blue and blonde, it must be covered at all cost. I love my blue hair as much as I love my pink hair. I seriously never want to be normal again.
