Overall, I think non-overdyed black jeans are quite versatile, though less so than indigo denim. I would say that black denim in which only the warp is dyed gives more of a charcoal effect, and just like with dressier attire, charcoal goes with just about everything, while black is often difficult to match. Overdyed black jeans are another story. My favorite options for the latter would be a white button-front shirt, tan or olive drab military shirt, or black or maroon t shirt.

That's interesting...the conventional wisdom is that "rules" for color matching (i.e. no black with navy, excepting ties and shoes) are more important for formal/business wear than for streetwear.
Not that conventional wisdom is always right or even meaningful.
