Good. I'm all for colours :-)

My point of view is that for printing, color is probably not the best
choice. However, for viewing PDFs online (as probably most PDF users
do, including me), I would really like to have colour support in code
listings.
Looking into `texinfo.tex` I was surprised to see that PDF output
seems to already have generic colour support (using the not officially
documented TeX macro `@setcolor{r g b}`). However, it would be
necessary to define a special version of the `@verbatim` environment
(similar to LaTeX's `minted` environment) that recognizes color
changes. This is certainly doable and probably not too difficult, but
I currently have other things to do. Maybe it's best to open an
issue.
