Do teachers grade more harshly when they use red pens?

Some interesting science to report...at least one presenter at every ASP conference mentions that students feel that red pen makes it look as if the paper is "bleeding" negative comments. A new spin: teachers actually grade more harshly when using red pen.  Another reason why green, pink, purple might be better bets when giving student feedback.
