Erebus looks pretty purple to me.
When was the last time you checked your eye sight . He's pale white / grey.
Zoom in on that screen shot. Look at his head. The only part of that which might be considered pale white/grey is the Bloom effect used to represent bright sunlight reflecting off of his purplish head. Conversely, the color at and near his chin and neck are probably not representative, as they may be modified by a shadowing effect.
Somewhere between his chin and the bright reflection near the top of his head and partly along one side of his face, is where we are likely to find the intended base coloration. Which looks a little purplish/blue to me.
More on-topic, Twin Blonde Female Assassins that look like that chick in that movie I can't recall the name of would work for me. Actually, I'm not stuck on blonde. Brunette, Redhead, Auburn, etc. all works for me. It's the twin part that makes this work.
