What can I wear with a pair of dark grey cable knit tights?

Red_Raconteur
I bought a pair of dark grey cable knit tights that look a lot like this link because they looked cozy and warm (they are). But now I can't make an outfit with them for the life of me.

What kinds of pieces should I be paring with these tights, and in what colors?
