Thank you Hugo (having finally found time to install and test this utility!).

multitail --mergeall -n 0 /var/log/access.log -n 0 -ci red /var/log/error.log

does just what I wanted.

It will even run commands at a specified interval and highlight the
changes in output:
multitail -R 2 -l "netstat -t"

For those with red-hat based systems (RHEL, CentOS, Whitebox...) then you
can get rpms from the Dag Wieers repository [1]. It's already in the
Fedora repository.
