I'm very, very particular about the sort of pens I like to write with. I'm very fond of very fine-tipped rollerball pens - the blacker and thinner the better, and they must have black ink. I think high school was what finally turned me off of blue ink - I almost hate it, and find it grating on the eyes. Black seems more definite, and it's sure as hell easier to read. I wonder how it is blue becaome the "accepted" colour.
