Hi.
I am starting to using MonoDevelop.
What is your favorite font and syntax highlighting style which is good to notice eye?
I am using MS reference Sans Serif font and Brown style.
Point another mono’s good option too plz.
I guess this is really preference matter , in my case i am in black screen + monaco font…XD
Hells Programmer at 6pt on a 30" portrait oriented LCD 
You can see almost a thousand lines** of code.
I had to hack the stupid Hells Programmer font to make it work with VS2010 because of the change requiring Truetype… GRRRRRRRRR
** Actual number of lines of code may vary depending on quantity of caffeine and/or alcohol consumed.
Is it possible to Change the Color and Font on a Pc ?
i prefer styles with a dark background as the white is a pain in the eyes 
when you look a while at it.
i use the consolas font.
when your question refers to monodevelop:
https://github.com/mono/monodevelop/tree/master/main/src/core/Mono.Texteditor/Styles
http://monodevelop.com/Developers/Articles/Syntax_Mode_Definition
http://randomland.net/tech/custom-monodev-theme
the font can be set under tools - preferences - text editor - general.
So I changed style to Oblivion (gray dark style).
And font is,yes your consolas font is good too.
Actually I have reviewed almost all font in MonoDevelop providing, and here I recommend some good fonts. And my personal valuation too.
