Well, something like "UnixHub" would have been reasonable: High contrast, large enough font even on a smartphone. (I'm not a fan of "mobile-only" themes, they usually lack continuity.)

Thank you, the "TheGray" theme is quite pleasant. :) (Minus the logo, but I know that this might not have the highest priority right now.)
If you have some time, you could add more darkness to the default font though.
