Amen to that!

Between the very low contrast, and the stereopsis whereby blues appear to
recede into the distance (and bright red pull forward, appearing to float on
top of the terminal), dark blue text on the background is nearly unreadable.

At my previous job, the solution to that was to ban changing the default
settings, but allow admins to create their own personalised defaults.

Fred would log in to the shared account, and run 

    source fred

to get his personalised settings. When George logged in to the shared account,
he'd see the defaults, not Fred's settings, and could run

    source george

to get his own settings.

(Obviously Fred and George would have to create the "fred" and "george" config
files first.)

I don't know if Windows shells have something like bash's `source` command,
but if it does, this would be one solution.
