I recently applied for the Schengen Visa at the German Consulate in Toronto. All of my papers were black and white. The guy at the consulate took a quick look to compare my original passport and the copy version, and returned the copy to me. So you will probably be fine, tho I can't speak for the German Consulate in other countries. I got approved in less than a week (applied on Tuesday, received my passport on the morning of next Tuesday)
