Purple, but not for passion

Cat had been proud of her long nails, of which she took great care. She'd painted them blue. The palette changed as she used them to scratch, lightly at first, and then increasingly frenetically all over her body. The blue was accompanied by a blood-red hue as she scratched through her skin and down to her muscles, silently screaming at Phil, who was beyond hearing anyway.

Her nails, acting like claws, were ruthlessly efficient in stripping her skin. She tore off the headphones, flinging them, together with Mac, over lifeless Phil, whose headphones were dragged off in the process.
