Normally when you add a user on a Debian system, the contents of /etc/skel/ are copied into the new user's home directory. But /root/.bashrc does not match /etc/skel/.bashrc and /root/.profile does not match /etc/skel/.profile. Also neither file is known to dpkg. So where do they come from?

You will need to play with the colours, but something like this should do the trick. Create the file /etc/profile.d/colours.sh with content similar to this:
#!/bin/bash
if [ $(id -u) -eq 0 >/dev/null 2>&1 ]; then
export PS1="\[\033[01;32m\]\u\[\033[00;37m\]@\h:\w\$ "

Found the solution, which was around permissions as I suspected. Somehow the setgid bit was set on /bin/bash.
The left system is the one with the problem, the right is a working one:

root's files are copied frombase-files: if they're missing, itspostinstcopies/usr/share/base-files/dot.bashrcto/root/.bashrcand/usr/share/base-files/dot.profileto/root/.profile. Additionally, if/root/.profilematches one of the recorded checksums (which means it hasn't been changed by the administrator), it is updated on upgrade.The same applies to
/etc/profileand/etc/nsswitch.conf(including updating on upgrade), and/etc/motd.
