I have two pairs of black jeans, both from Madewell. (One quick note: I usually cannot wear high-rise but Madewell high rise work really well on me.)
One is a pair of true black high rise coated skinny jeans, which feel dressier to me than regular denim, and one is a pair of kind of washed black high-waisted button fly released hem cropped flares. I love them both. I actually love wearing black tops/sweaters with both, even if / especially if the blacks don't match. You can get a great tonal look with a variety of blacks. For me, black denim is edgier and more rock-ish (if that's a word), a bit more James Dean, a bit more interesting than blue. It's the edge I think. I've never had an issue with dye or anything.
And the button fly ones, BTW, are a recent purchase and fit like a dream. They are more casual (released hem, etc.) but if you are interested, I sized down one size. They are the only jeans I have ever owned where I didn't need a belt. They fit like a glove and looked terrific with booties.
