Aura radiated
From Graal Bible
Delterian RP term for having pink hair. The RP implications of this are that the wearer is a member of Veracity and the wearer worships Goddess Marissa. Tortoise literally radiates excess aura energy, so when a person is overexposed to Tortoise and they worship Marissa, they will typically switch hair color. This parallels what actually happens in reality: as people hang out with Tortoise, they tend to change their hair around.
Interestingly enough, Tortoise usually makes people make their own heads. This has resulted in about five different styles of hair color, but it all accomplishes the same purpose.
