If you really are insisting on a logical explanation, consider that in the Drow's current environment, pretty much everyone has eyes that work the way Aristotle thought eyes work. Instead of eyes receiving ambient light reflecting off surfaces, creatures with Darkvision emit light from their eyes much like radar. As such, there is an evolutionary reason to maintain pigmentation. Perhaps the black skin evolved to partially thwart Darkvision.
Psued-logic is okay. But that might also work well with why Drow have disturbing red eyes.
