I really enjoyed knitting these socks. They were the first toe-up pair that I really felt comfortable knitting (and didn't have to re-do the heel numerous times).
The pattern is Ribbed Ribbon Socks from Wendy Johnson's new book, Socks from the Toe Up, using Oceanwinds Knits sock yarn (in a forgotten colorway) on size 0 needles. Very nice yarn by the way.
The actual color is somewhere in between these two pictures.
