Header line is unreadable in macOS Terminal

[stesser]

In the macOS Terminal the header lines are unreadable. They are displayed with dark red letters on a dark blue background. I have checked the display using different TERM environment settings and with TERM unset, and I do assume that the TERM setting is actually ignored.

The source code contains:

let normal_style = Style::default().bg(Color::Blue);
...
                   let style = Style::default().fg(Color::Red);

Therefore, seems "it works as designed", but the design does not lead to readable text on my display (since both red and blue come out way too dark, at least on my display) ...

Thank you, commit 76d257a seems to work just fine:
