script/server log - use colour to highlight errors?

Hi all,

Is there a way of adding colour to the script/server terminal log, so
that issues and errors can easily be spotted?

When working locally, I often glance at the terminal screen to catch
'ActionController::RoutingError' messages, '500' errors and so on - I'd
love to for these issues to be higlighted in red so they are more easily

At its simplest, I imagine this to be a case of where the terminal spots
certain keywords and then makes that line bright red for example.

Is there anyway of doing this?
