I would be nice to be able to configure the colours used. Would need a PR against systemd I expect to get this changed. One hack would be to edit the output and replace the escape sequence for the poor colour to use a replacement using sed I guess. For example change the blue to red. SYSTEMD_COLORS=16 journalctl | sed 's/\x1b\[0;34m/\x1b\[0;31m/g' | more I use more not less and notice that less does not show the coloured output.
