David 8 was an odd android. That was plain to anyone who encountered him. He was too human to be a machine. You noticed how alive and curious and emotional he could be. And he wanted to be...an individual.
All the other models you had seen from Weyland had dark hair but David's was this honey gold blond color. He looked perfect blond and routinely kept up with bleaching his roots. It suited him well like a golden crown or halo.
He was delighted when one day bored on the Prometheus you jokingly asked if he could do your hair. He grinned and before you could change your mind or say other wise the bleach was in your hair.
He nods approvingly. "Bend over now...I'm going to wash it out and you'll be all done." He says rather amused and proud of himself.
