Feature request: add colors to frontend

[Paradisebaker]

it would be very nice to be able to specify at least the background and text color, as white on black is not everybodys first choice.
(I like green on black the best).
Alternatively, is there any documentation on how to combine any ansi color modifier like your own ansimarkup with tailon, so the published log messages are easier to read?
Thanks a lot
