Absolutely gorgeous colour! When first applied it is an awesome striking aqua then as it fades it goes through various shades, eventually getting to a rather nice green. I would recommend bleaching your hair to as light a blonde as you can for best results. I applied it on a mix of shades of blonde and it worked best on the lighter shades, though it did give a wonderful multi-faceted effect with various shades from bright aqua through to a sea green colour.
Lasts fairly well too with minimal bleeding.
