Colour and HTML signatures in Mail.app
A tip on macOSXHints shows you how to create a coloured signature 
in Apple Mail.
This only works, obviously, if you email in Rich Text.
In the comments, another poster links to the older macOSXHints tip on creating more complicated HTML signatures , saving them as web archives and manually copying them into your Mail folder.
Or you could follow this tutorial on inserting a graphic into your signature provided by a Skype user, but useful for any graphic not just Skype promos. (You could, but now it requires you to log on with a Skype account. Shame.)
It goes without saying that restraint and good taste are crucial in this matter. Don’t do this.

I don’t think so :(
That is to say, I don’t think that it is worth the effort.
You could do it by using an external text editor like TextMate and inserting the emoticons as images hosted on a remote server somehere, but you would have to be pretty keen.
