When composing an email or answering thereto, simply mark the text section you would like to color, choose "set text color" from the icon menu bar (located between the address/subject area of your mail window and your email text) and that's it. And of course, you could set different colors for consecutive replies.
But I'd have to do that for every email? No automatic way to set them? My business has me doing maybe 500 emails a month. :-)
Oh wait, it's not as complicated as I thought. Wonder if I can set that up with custom colors?
