The only known Rainbow Drinkers are Kanaya Maryam and Porrim Maryam. However, The Dolorosa may have been a rainbow drinker, as her eyes are seen to glow a bright yellow when she hisses at john. Rainbow Drinkers have white skin that normally glows. However, as seen with Porrim and later Kanaya, some Rainbow Drinkers can turn off this glow. Their scleras appear bright yellow instead of the usual orange. Currently, the reason for this is unknown.
