Yes, for example

   echo 'warn 38;5;72' >> /etc/terminal-colors.d/dmesg.scheme

works. The \e[ m is unnecessary (we follow coreutils dir colors
semantic).

  alert 38;5;16m\e[48;5;202

works, but in this case more consistent and readable notation is probably

  alert \e[38;5;16m\e[48;5;202m  

that works too. 

(The result is orange background and black foreground, right? :-)
