I've tried divided substrate multiple times in the past and I always end up redoing it because I found it was a hassle to maintain. I usually always have cories so they tend to be the main culprit behind the inability to keep everything separate, but not being super careful during water changes/cleaning and moving around plants also contributed. I'd say it will depend on what you choose for the black substrate.
