there is such a thing as a black iris. It's so dark purple it appears to be
black. I have them thanks to Mary Emma, a dear gardening friend and
mentor/mother person. Mine have bloomed "black" now for three years. You
won't have to do anything to "keep them black" as they're genetically this
way.

In fact, there's even a wild species of iris that always extremely dark
purple-to-black. It's native to the Negev Desert.
