Are you sure?  I use SciTE, and its output pane does have highlighting
done by Scintilla.  I have done practically no Geany configuration, so
I don't know how you would "port" these settings (and in fact there
may be some things that are SciTE-specific, and thus not portable to
Geany), but what SciTE has in its others.properties file is

lexer.*.err=errorlist

# Error list styles

style.errorlist.32=fore:#B06000,$(font.small)

style.errorlist.33=$(font.small)

lexer.errorlist.value.separate=1

So I'd bet there is some way you can leverage Scintilla to do this in Geany.
