I generally keep the font and color the same, it's easier for me to read if I go back to it. I'm not really sure why it's easier for me to read, but I tend to have some issues reading certain shades of colors. Also, I don't really like to mess around with the color or anything because I have trouble enough typing with the fact my laptop tends to zoom in a lot or zoom out when I'm trying to type, so I try to type what I want to type as fast as I possibly can. xD
