So I went for blue, and purple. My blue socks are some that are getting worn, and I have no purple socks. And here they are!

Sadly, although the blue is pretty close to the in person colour, and so is the variegated purple, the other purple looks darker and more plummy in person than it does in the photo. I don't know if it's just my camera, or the photo program, but it really has difficulty accurately depicting some of the colours that have red or purple in them.
