Supposedly, 10% of males are red/green color blind as are my father
and both of my sons. I used red pens to grade papers. And, I still
like red (or pink) to make notes on my own documents. But, now I

chromatically-challenged, green ink looks almost gray. Blue has better
impact. (Thank goodness they hang nice red and yellow lights on street
signals so I can locate the one they say is green.) -Kevin
