The log can be very substantial and it would be nice to have some lines brought to attention by a different color. As a text file, the log can’t have colors. Only the output to your terminal could have ANSI color codes. I’d welcome this, too, but then we need additional configuration, color breaks easily on some shells, the feature should adhere to the usual shell variables etc. Don’t know it it would be worth the effort.

There is no need to patch the engine for that, just some extra lua code that Hans has to be willing to write/include. However, if support for redirect of stdout is needed (because in that case the ’term’ in internal TeX speak is not really a terminal), then isatty() needs to be exposed to Lua in one way or another. If you want color in the actual log, then someone has to rewrite the log reporting lua code to generate RTF or HTML. Should technically be doable as well... BTW, it is not safe to assume that all ttys actually support ansi colours (remote terminals quite often do not), so a command-line switch would still be needed.
