Meh, the black looks dumb. Robocop is a walking tank, not a roboninja. And the glowing red visor, which looks stupid and cliche all on its own, also completely negates any tactical stealth the black suit might give him.
"Where do we shoot him?"
"Aim just below the red line!"
Also, did the re-makers not catch the oh-so-subtle satire of the original? It's like they cast around for yet another tortured "superhero" to make into a super-serious summer action movie and someone saw the Robocop DVD gathering dust on a producer's movie shelf and said, "There's our next fast cash grab, gentlemen! Make that, but with more flash and tacticool gadgetry and 'splosions! No, no, no, don't watch it. Just print off a description from wkipedia or something to get the barest idea of a plot and roll with it."
