Multiple fonts for headers

Hi there!

I am currently working on a magazine theme for my website and I want it to look really editorial, so I want to the following: use shortcodes or custom fields to be able to control the font for each post header. Example: a post “White Horses” will have its title in Arial, but a post “Black Horses” will have its title in Courier.

I want to use different versions of one font but… I don’t know how to do such a complex thing.

Can anyone help me? Or is there some plugin for it?

Thank you very much for any comments!
