Parisine from Porchez Typofonderie

Yours truly, writing for Typekit:

Parisine STD Clair is a simple, elegant sans with an expressive (and hefty) counterpart, Parisine STD Sombre. Both styles come in two weights, with italics. To compare these two styles of Parisine is to study the economies of designing a type family with extreme weight differences, while maintaining a family affinity. The counters not only differ in shape, but shift their balance; the contrast increases with thickness; and the letterforms bend, not only to accommodate thicker strokes, but to preserve the balance between positive and negative space.
