clang colorized html output

I love that clang has COLOURS in its output, but how to keep this formatting when copying the output to a file?

The solution is simple, add a -fcolor-diagnostics option and pipe the result to ansi2html. Of course since most of the interesting output is on stderr, don't forget to correctly redirect it (2>&1).

So in the end

$ clang -fcolor-diagnostics temp.c  2>&1 | ansi2html > temp.html

Many thanks to nemo for sharing this trick and several others on this blog!
