okay sorry I'll point u then
you could use a simple prog like
eydropper (link here) to get the colour to change ur font to.
if your after some other person's font then it will already be installed on ur comp otherwise you wudnt see it and would just see a default font such as arial therefore u should just be able to select it in the choose font dialogue....
however it would be cool to steal a colour from someone's font with a simple command
