Hello everybody. I'm designing a contemporary, Elzevier-inspired serif typeface and now I've come to a rather interesting point—old-style figures. Normally you'd expect a stressless zero that's almost monolinear, but that it relevant for the basic "Regular-Bold-Italic-Bold Italic" model. I have a Light and a Black master—that's a kind of a problem, because in black, such monolinear stressless zero is too light and too out of style. I suppose that I could use other solutions for old-style zero such as bottom point raised above the baseline and/or reversed stress. What do you think?
