audit logs quite hard to see with standard VT colors

Since https://github.com/systemd/systemd/commit/194da5ca5159597e4fac726db5cee104ec338213 (thanks to Kazuo Morikawa for finding the commit), systemd colors audit logs in 'ANSI blue' by default. On a VT on a stock Fedora install - which I think will be the same on other distros and *nixes - this is quite hard to read, as the blue used for 'ANSI blue' is a pretty dark one, and the background color is black.

On Fedora with GNOME Terminal the default color palette is 'Tango' with color scheme 'Tango Dark' and with this combo a medium-light blue is used on a dark grey background, so that's quite readable. I don't know about other terminal apps. But it's definitely pretty bad on VTs.

It's difficult to pick colors that work for everyone all the time, but being hard to read on a VT seems bad :/

Here's a photo of my screen. If anything, the photo brightens things a tad and makes it look slightly easier to read than it is in person.

Start by reviewing commit 194da5ca5159597e4fac726db5cee104ec338213 and reproducing the audit-log colors on a stock Fedora virtual terminal and in GNOME Terminal. Compare the default palette behavior and determine a color choice that keeps audit logs readable across the reported terminal environments.
