toner, not a pigment
"Virgin Snow is a subtle ultravoilet toner, ideal for blondes and platinums as a finishing or upkeep product to reduce yellow undertones. This pigment is not for those seeking a change in color or hoping to neutralize visibly copper or orange hues. Fans of purple shampoos and purple conditioners may appreciate Virgin Snow as a color-bomb leave-in-treatment version of the toning products they're familiar with. Dye-Hards seeking more pigment to remedy their yellow and orange hues in one session may find more success diluting a Classic Manic Panic purple pigment to a stronger saturation than Virgin Snow."
