Great question!

There is ansi2txt (packaged as colorized-logs on debian).

I also found some answers on SO with people using a sed command for this.

Often, `cat` will do that. Many tools look at stdout to see if it's a terminal. When it isn't, they suppress color output.

By itself, less will prevent any control sequences (including colours) from actually being sent to the terminal, but most distros seem to have -R set on it by default these days. If you unset -R it'll do exactly that.
