Well actually, Alex has always had a pinkish complexion, even before gorgeouspil. That's how it goes with some asians.
Usually an asian model can look completely white, depending on the lighting. Like the girl, Zhang Ziyi, who was in Crouching Tiger. She looks white most of the time. Most people probably think she is half white or completely white by most of her photos.

It depends. Have they been out in the sun. Asians will generally turn completely white if left indoors.
