I already owned a black one of these and love it and I wanted a white one. I saw the "tusk" color online, which looked very close to white. When it came to my house, it was tan/light brown - nowhere near white. It depends on your computer because I pulled it up on my smartphone and it did look tan there. Both of my laptops that I own showed it as being very close to white. The quality of this coat is awesome, I absolutely love it.
Also, it runs a bit small. I usually wear a medium but for this coat, I wear a large and it fits pretty good. Just might want to keep that in mind.
