One trick is to use your mouse to highlight the text, so it becomes white on blue, a slight improvement over green on black.
From the front view, no one is going to mistake (usually) a man from a woman; Or a femininely dressed (e.g. skirt dress) woman with short hair for a man, However, if the women dress very androgynous, and with very short hair, it's easier to be mistaken as the other gender, especially from the back. I have definitely made that mistake before (as matter of a fact, I've mistaken a man for a woman who had a nice long head of *gorgeous* hair that any woman would admire, until "she" turned around. lol.)
Call me weird, even though I am not a girly girl, and I have had my share of short hair cuts in my life, I've always made sure that I don't get a man's hair cut, because I don't want to look like a man from the back! Just my personal preference. FWIW.
