I NEED a sock project

I'm going to make this quick because I should be getting ready for class, rather than posting. The semester starts today and I will be taking Accounting and Marketing (both intro level classes). This means that I NEED a new sock project. There is always time before class, after exams, (during really boring lectures...) for a bit of knitting if its a) a small project and b) easy to pick up and put down. To me that means socks. So maybe this afternoon I'll pick out a pattern (I already know its going to be from New Pathways) and some yarn. Thats where the decision making gets harder. Which yarn? What color?
