Color
Personally, I like to use teal due to it's resemblance to the color of my characters right eye, as well as it is my favorite color.
Font
I formally used Times new roman, however I sought a more unique, and less used font, so I opened up gimp and looked through all the fonts and wrote with them, and I grew partial to the Sans font, I am not too sure why that is, however I have used it ever since.
Style
I always try to center my text, make it teal, and make it Sans. Sometimes I have issues with coding and I have to leave out the font code, however I try my best to not allow that, due to my OCD when it comes to the appearance of my posts.
