Not in any text widget that I have heard of.

Once you decide how to encode this information into the text it should be a
pretty simple matter to render the text in different colors, by modifying the
AsciiSource in the Athena text widget.

I didn't feel that it was worth trying to come up with a text encoding with
color information, so one color is all you get.  Once you have the encoding
telling the text widget to do the right this should be trivial.
